I'm experimenting with creating a metro style app with Visual Studio 2012, I am not the most experienced designer but one thing with my applications is confusing me.
I have been working with 'basic pages' instead of blank ones for the different pages in my application for design consistency, however it seems that these 'basic pages' have a strange behaviour. Every item I place on the page (buttons, text boxes, etc) will all slide in one by one when the page opens. For example if I run the application and navigate to a page with 10 buttons, it will do a brief animation where each button will slide in from the right side to the left side. When dealing with a large number of items on one page this can take a lot of time as each item slides in seperatley.
Looking at the properties for each item I have been able to change the direction it slides in while loading the page by changing the flow direction. Also with a bit of research I am thinking it could potentially be due to either the metro style 'enterPage' or 'enterContent' animations, though I can not be certain.
I have tried to experiment and figure this out, and search to find out what causes this so I can modify it (Ideally I would like to just group items together to slide in with each other) however it's kind of a difficult thing to search with vague words, so I'm asking here.
What is causing this and how might I go about modifying it?
EnterPage shouldn't be sequencing the animations. They do offset some of the animations of a number of elements, but it shouldn't be each one sequentially.
Are you using WinJS navigation?
Well after a bit of experimentation I figured out that putting all my page content inside a grid made them all come in at once like I wanted. I probably should have tried that earlier but everything was already inside an outer grid for the page, so I thought that woulda handled it.
I don't quite understand it fully, but that works for now.

Improve this question
I'm writing an internal-tools webapp; one of the central pages in this tool has a whole bunch of related commands the user can execute by clicking one of a number of buttons on the page, like this:
toolbar http://img709.imageshack.us/img709/1928/commands.png
Ideally, all of the buttons would fit on one line. Ordinarily I'd do this by changing each widget from a button with a (sometimes long) text label to a simple, compact icon - e.g.
button labelled "Save" http://img337.imageshack.us/img337/773/saver.png
could be replaced by a familiar disk icon:
Unfortunately, I don't think I can do this for every button on this particular page. Some of the command buttons just don't have good visual analogs - "VDS List". Or, if I needed to add another button in the future for some other kind of list, I'd need two icons that both communicate "list-ness" and which list. So, I'm still considering this option, but I don't love it.
So it's come time for me to add yet another button to this section (don't you love internal tools?). There's not enough room on that single line to fit the new button. Aside from the icon solution I already mentioned, what would be a good* way to simplify/declutter/reduce or otherwise improve this UI?
*As per Jakob Nielsen's article, I'd like to think that a dropdown menu is not the solution.
Edit: I'm not looking for input about the icon idea. I'm looking for other solutions. Sorry my example disk icon was a small one; it was just an example. I'm showing a bigger one now to hopefully be more clear.
I would add a More Link Like Google does.
See the Top Bar of Google with WeB Images Map More >>
To this more >> drop down you can add logic to add button less frequently used by user or something like that.
If you read Jef (and Aza) Raskin, you'll probably realize that icons are also not a good solution – both were pretty vocal in their dislike for them (with very few notable exceptions). For a start they're even harder to hit than tiny buttons, then their symbols can be confusing, culture-dependent and misleading. We're already good at reading text, parsing and interpreting icons is often slower.
In any case, that button bar looks like it accommodates pretty much anyone and their dog who might be using that product. You might have had some specific scenarios in mind when creating it that should be easy to do and are important. Most likely not all buttons are needed at once for such a task to complete.
Another thing is that maybe not all buttons are even useful at any single state of the application. Can you maybe branch into different sets of buttons, depending on the state. That's only possible however, if each state has clearly defined what actions can be taken. If all buttons are equally pressable regardless of state this won't do anything.
Grouping commands according to related functionality might also be an option. This doesn't have to be done with menu-like idioms, you can also put them into containers with different background color or even color the buttons themselves (just keep in mind color blindness, though). Depending on how related those individual functions are this can be a good way of speeding up interaction. It might requier some training for users to know what the colors refer to but for an in-house tool that's only used by people you know (instead of by arbitrary random ones [which is a problem Microsoft faces quite prominently]) this should pose not much of a problem.
What if you use icons and text?
For the commonly understood commands - use just an icon (like the save)
For the uncommon commands use an Icon + the text.
If you put a border around the button as a whole it should tie the icons / text together nicely and show it's still a button. You could also do some hover effects.
Since you can't do a dropdown menu (or similar techniques like clicking a button to generate a secondary menu). The best I can think of is what Prescott did or showing an area of buttons that are grouped in such a way to make it easy for the user to know which section their button should be in.
I would start by changing some of the longer labels. At a minimum, "Application Loading" could be abbreviated "App Loading." What's another (shorter) way to say "Quick File Transfer"?
You could also group the buttons into tabs (i.e. make it a ribbon). That might work particularly well if different classes of users tend to use different, non-overlapping sets of buttons.
Numerous options:
Group and labeling. Any time you have more than eight commands, you should divide the menu items into semantic groups of about four to help the user scan for the command they want. Labeling the groups also helps the scan and can make the menu more compact. For example, Instead of VDS Ping and VDS List, Have a group labeled “VDS” with “Ping” and “List” menu items. You’ve one less word to fit in (two if you put the label above it’s associated menu items when using a horizontal orientation).
Pulldown menus. Nielsen is correct about avoiding the use of a dropdown menu for making commands. However, he’s clearly in favor of pulldown menus which look and behave like a menubar in a thick client app (Nielsen calls them “command” and “navigation” menus). I think you’ll find that there are several Javascript pulldown menus out there now, unlike back in 2000 when Nielsen wrote his post. You can fit 100s of commands in a menubar.
Sidebar menu. Arraying the menu items vertically and you should be able to fit 20 or more commands and you won’t have to shorten any command names to something user might not understand. If that’s not enough, consider a “menu bank” than combines the benefits of sidebar menu with the capacity of a pulldown menu.
Ribbon. If your commands fit into discrete tasks, where the user tends to stick to one task for a while, you can arrange the buttons on a tab control, with one sheet per task.
Command Overloading. Represent your data objects as selectable entities in your window and change your commands into more general operations, like Drill-down, Create, Copy, Move, Delete, and Link, that can be applied to various different classes of objects, thereby reducing your total number of commands. The user can select one or more data objects then select the desired command to act on them.
Work Area Attributes. Some of your commands may not be commands by settings or attributes. Remove them from the menu and represent them as data objects in the work area of the page (or another page, if they are rarely used) using controls like radio buttons, dropdown lists, and check boxes. This has the added benefit clearly showing the user the current setting as well as providing a means to change it.
Variants. For an internal app, you probably have formal roles and responsibilities that vary by work position. Include the user’s position in your model, and dynamically hide commands (and other controls and pages) that aren't relevant to that position.
What about a combobox and a Confirm button?
Or a simple dropdown menu?
Add a "Tools" or "Actions" menu bar, and stick rightmost 4 commands (or more) into the menu.
Would it be possible to implement a "most used" or "preferred" set of buttons (preferably for the user, but globally if necessary) and button to take you to the rest of the items if you need one of those?
You could group them (like the two 'vds' buttons) behind a single button that, when clicked pops a context menu with the individual icons.
It truly seems like what you're developing is a administration console which happens to present its UI through a web page, rather than something which I'd quantify as a web app. As such, especially given your statement that this is an internal use application, Jakob Nielson's advice regarding <select> tags being poor design need not apply.
For this particular set of assumptions, I think the better option is to imitate a system menu setup using one of the many CSS-based menuing designs possible.
Icons are terrible from a user experience stand point. A picture of a Floppy Disk doesn't un-equivocally mean SAVE. It means something to do with a Floppy Disk. A Floppy really, its 2010, SAVE on a web app means save to the server, how does a Floppy Disk even compute?
Here is an application that has had the same extremely usable interface for 10 years! And hardly any images for buttons, and it is one of the most productive applications in its category.
You know what ICONS stand for I ncomprehesible C ryptic O bfucsated N onsense S ymbol!
Also how do you internationalize an icon?
In a project I'm working on, we have a nav menu where items are colored when the relevant section has information beneath it, or faded when there's nothing available to the user. In the case of an admin, these items may have no useful information but may still be clickable (since things like "Add news item" or "Add file" are implemented as sub-menus).
The call from On High has come down to make these admin items stand apart somehow. Since we're already using the faded text for unclickable items, I was wondering if there's an established UI convention for denoting that an item is clickable, yet contains no information.
And yes, I've already asked why we're bothering to show items that aren't available to the user. The short of it: because On High wants to.
Short answer, no I don't think there's a convention for this. Lots of people would say if its not applicable, don't show it. However, there's some debate on this. One of the reasons Microsoft started using The Ribbon in MS Office is because they wanted to get away from dynamic menus where options hid and showed 'intelligently'. Users couldn't figure out the rules for what appered where, and when.
Maybe separate the concerns here: 1) how to indicate the item is clickable, and then 2) how to indicate the item contains no information.
The first one is relatively well established -- blue underlined text. You can also make it look like a button Of course, if you've got a site-specific look for your hyperlinks, use that. Basically don't break the users' expectiations of what things are clickable.
Second, how to show there's nothing there worth clicking on. I think what you want is some visual indication of the priority/utility of these admin links relatively to others. Some options:
Can you move the admin links to the bottom of a list?
Add a number indication how many things are on the other side of the link?
Strikethrough on the text?
Since there are no hard-and-fast conventions on this sort of thing, just remember that anything you do which is consistent will work. Some things will just work better than others.
No matter what you choose, the user will learn after a few tries what the new method of empty indication is.
If it is well thought out and consistent, they will probably get it after a couple of clicks.
Also, remember that too many highlights, colors, fades, and underlines will wash out any amount of effectiveness at visually organizing your menu so it is easy to use. At some point it can actually get harder to use by over-organizing things.
Think about it this way: There are two boxes sitting on a virtual shelf. One is red and the other is blue. The selected box is identified by a differing color than the other box... Now, which is the selected box?
Often times convention is one of the most important design consideration for user interface. Usually the advice goes to do it like Microsoft does.
This is for three reasons:
If it ain't broke, don't fix it.
If your users expect to click on a floppy disk icon to save, don't change the icon (even though some of them may have never seen an actual floppy disk).
Users don't want to re-learn the interface (and hot keys, etc.) with each different application they use.
At the same time Emmerson said "*A foolish consistency is the hobgoblin of little minds.*" So when does maintaining a consistent user interface cross the line from a good idea to stagnated innovation?
Microsoft shook up the good old WIMP GUI with the introduction of the tool bar, and then again with the Ribbon control (which is the natural evolution of the tool bar, like it or not.) Now we are seeing ribbons everywhere.
So my question is, what are some user interface paradigms that are accepted and consistent across multiple applications, but have stayed past their prime and are starting to reek? Are there some important changes that would benefit from a grass roots push by developers to innovate and improve the user interface experience for our users?
One thought that came to mind for me is the modal pop-up dialog. You know the ones that say: "Are you sure you want to . . .. - [Yes] [No] [Cancel] [Maybe]" and its evil twin "Successfully completed what you wanted to do! [OK]." We are seeing a movement away from these with the "info panel" in browsers. I think they need to be adopted in windows application development as well.
If possible please list a solution for each stale UI item.
And please don't list clippy. We all know he was a bad idea.
NOTE: This is specifically Windows client user interface paradigms, but I am certainly open to drawing inspiration from the web, the Mac, etc.
You mentioned popup modal dialogs , and I'd argue that non-modal ones are just as bad. Any dialog box remove focus from the program, they could end up behind the program and make it hard to find it, they might not even appear on the same virtual screen.
I'd like to see an end to all dialog boxes. If you need to stop someone from using the UI because of some non-normal circumstance, then remove the relevant parts of the UI from the window, and replace it with what the dialog would contain. Bring back the UI once the problem has been handled.
Clicking things on touch interfaces
It's incredibly difficult to click on things on a touch interface, because you don't know when you have pressed the screen hard enough. And if you add an animation to the button you are clicking, you most likely wont see it, because your finger is in the way. Adding other reactions, like vibrating the phone or painting waves on the screen might work, but there is usually a delay which is too large, much larger than the tactile sense of a button being pressed. So until they invent a screen with buttons that can be pressed, all touch devices should move towards dragging user interfaces (DUIs) instead.
Counter intuitively it is easier to press an object on the screen, drag it, and then release it than it is to just press and release it. It's probably because you can see the object moving when you start dragging, and you can adjust the pressure while dragging it. Dragging also has a lot more options, because you now have a direction, not just a point that you clicked. You can do different things if the user drags the object in different directions. Speed might also be used, as well as the point where the user releases the object. The release point is the real strength of DUIs, because it is very easy to release something, even with pixel precession.
Some designs have started to use DUIs, like (here we go) the iPhone, palm pre and android phones. But only part of their design is DUI, the rest is clicking. One area they all have in common is the keyboard. Instead of clicking on a key the user presses any key, then drags their finger towards the key they really wanted to click. Unlocking these phones also uses dragging.
Other easily implemented DUI features would be things like mouse gestures, where dragging in different directions, or drawing different shapes does different things. There are also alternate keyboards being researched which puts a bigger emphasis on dragging. All buttons can be changed into switches, so have to drag them down a bit to click them. With a well designed graphics, this should be intuitive to the user as well.
The Apple Human Interface Guidelines are a good read on this topic. They discuss this from a very broad point of view and the guidelines apply to any platform, not only Mac.
The file system. I want to save a file.. >OOOPs I need to think of a file name first. Well.... how about ... blah.doc.
6 months later...
Where the %#*(%& * did I save that %()#*()*ing file?
The solution is build a versioning system into the application, or better, the OS. Make files findable by their content, with a search engine, instead of forcing the user to come up with a memorable name, when all they want is for their file to not get lost.
Eliminate the save step. Type something in to the application, and it's just there, and there's no risk of losing it by some misstep, like forgetting to save. If you want an older version, you can just pick a date and see what the document looked like back then.
To build on the search engine idea: It's a pain having to navigate some arbitrary tree structure to find your stuff. Searching is much easier. However, you might still want to have something like a "folder" to group multiple files together. Well, you can build a richer metadata system, and have a "category" or "project" field, and setup the search engine to show items by project, or by category. Or group by those, or whatever new UI discovery we make next.
This question is a bit too open-ended, IMHO.
However, my main approach when designing anything is:
Fits in to wherever it is. If it's a windows app, I copy MS as much as a possible
It's simple.
It provides options
Buttons have a nice description of what the result of clicking will be, as opposed to 'yes or 'no'
Harder to answer the rest of your post without spending hours typing out an arguably useless (and repeated) set of guidelines.
In my mind, the one thing that really stands out is that USERS need more and easier control over the application's user interface appearance and organization.
So many interfaces can not be modified by the user so that the most used/favorite functions can be grouped together. This ability would make your favorite software even easier for you to get things done.
Error messages need a "Just do it!" button.
Seriously, I really don't care about your stupid error message, just DO WHAT I TOLD YOU TO DO!!!
I think the entire Document model of the web needs to change. It's not a user interface, but it leads to many, many bad user interfaces.
The document model was a good idea to connect a bunch of documents, but now the web is also a collection of applications. Today, I think the Page/document model corrupts our thinking. We end up lumping things together that aren't related, modularizing our code wrong, and in the end confusing users with our monolithic control board type websites.
Find dialogs that sit over the widget in which you are doing the search are terrible. Loads of apps do that. The find bar in Firefox works much better.
Many applications have multiple panes within the UI - eg in Outlook there's the preview pane and the inbox pane (amongst others). In these applications typically cursor key presses apply to the currently focussed pane. But there's very poor hinting to show the user which pane has focus and there are seldom keyboard shortcuts to move the focus between panes.
The focussed pane should be highlighted somehow.
Something like alt+cursor keys should move the focus around.
Ctrl-Tab and Ctrl-Shift-Tab cycle left and right through tabs instead of MRU behavior, even though in most cases the same behavior is duplicated with Ctrl-PageUp and Ctrl-PageDown.
There are a lot but here's an idea for a couple of them:
Remove some clicks like in "add another" or "search item" and the like.
This is well done with interfaces like ajax which have autocompletes ( and auto search ) but is slowly being adopted for platform UI's ( and in some cases they were originated in platform UI's. )
This is how StackOverflow does it for some scenarios.
But of course, we all know that already don't we? No need for "Seach tag" or "Add another tag" buttons, they just happen
Dialogs as you described.
Guys at Humanized proposed Transparent messages which actually are used in their product Enso and some other places.
Mac uses them for notifications ( like in Growl ) use them very well, or Ubuntu new notification system.
alt text http://blogs.sun.com/plamere/resource/NowPlayingGrowl.png
Firefox replaces the traditional "Search" dialog box with a search bar at the bottom.
Although not everyone likes the placement for next/previous as in this screenshot
And even SO ( again ) :) replace the notification with the yellow bar.
Finally:
File managers
I really like ( sometimes ) the simplicity of regular file managers, but some times I would like to work faster/better with them.
If you compare IE 4 with IE 8 you can tell the advance ( even better compare IE 4 with Google Chrome )
But if you compare Windows 95 Explorer with Win XP they are almost the same!! ( Win Vista/7 is a step forward )
But I wonder: Why haven't file managers improved as much as webbrowsers?
That's one reason I like stuff like QuickSilver but it is just a step. Much work is needed to create something like a "Perfect program launcher" or (FileManager/DesktopSearcher etc as you wish )
QuickSilver featuring "move to" action

What techniques do you know\use to create user-friendly GUI ?
I can name following techniques that I find especially useful:
Non-blocking notifications (floating dialogs like in Firefox3 or Vista's pop-up messages in tray area)
Absence of "Save" button
MS OneNote as an example.
IM clients can save conversation history automatically
Integrated search
Search not only through help files but rather make UI elements searchable.
Vista made a good step toward such GUI.
Scout addin Microsoft Office was a really great idea.
Context oriented UI (Ribbon bar in MS Office 2007)
Do you implement something like listed techniques in your software?
Edit:
As Ryan P mentioned, one of the best way to create usable app is to put yourself in user's place. I totally agree with it, but what I want to see in this topic is specific techniques (like those I mentioned above) rather than general recommendations.
If you do give the user a question, don't make it a yes/no question. Take the time to make a new form and put the verbs as choices like in mac.
For example:
Would you like to save?
Yes No
Should Be:
Would you like to save?
Save Don't Save
There is a more detailed explanation here.
Check out the great book Don't make me think by Steve Krug.
It's web focused but many of the conepts can apply to anything from blenders to car dashboards.

User patterns
Designing for scanning
Wise use of copy

Place Users in Control
Use Modes Judiciously (modeless)
Allow Users to use either the Keyboard or Mouse (flexible)

Promote Visual Clarity (organize)
Make the Interface Consistent
Sustain the Context of Users’ Tasks (continuity)
Maintain Consistency within and across Products (experience)
Keep Interaction Results the Same (expectations)
Provide Aesthetic Appeal and Integrity (attitude)
Encourage Exploration (predictable)
To add to your list, aku, I would put explorability as one of my highest priorities. Basically, I want the user to feel safe trying out the features. They should never back away from using something for fear that their action might be irreversible. Most commonly, this is implemented using undo/redo commands, but other options are no doubt available e.g. automatic backups.
Also, for applications that are more process-oriented (rather than data-entry applications), I would consider implementing an interface that guide the user a bit more. Microsoft's Inductive User Interface guidelines can help here, although you need to be very careful not to overdo it, as you can easily slow the user down too much.
Finally, as with anything that includes text, make the user interface as scannable as possible. For example, if you have headings under which commands/options appear, consider putting the action word at the start, rather than a question word. The point that Maudite makes is a good example of scannability too, as the "Don't Save" button text doesn't rely on the context of the preceding paragraph.
A useful technique which I never see anyone use is to add a tooltip for a disabled UI control explaining why the control is disabled. So if there's a listbox which is disabled and it's not clear why it is disabled, I want to hover over it and it tells me why it's disabled. I want to see something like "It's disabled because two textboxes on the screen were left blank or because I didn't enter enough characters in some field or because I didn't make a certain action.".
I get into sooooo many such situations and it's frustrating. Sometimes I end up posting in the software's forum asking why a control is greyed out when a tooltip could have helped me in a second! Most of these software have help files which are useless in these kinds of scenarios.
Try to pretend you know nothing about your software and try using it. However this is not practical because you already have a certain mind set towards the app. So watch fellow developers or friends use the app and look out for the pain points and ask for feedback.
One of the classic books to help you think about design is "The Design of Everyday Things" by Donald Norman. He gives great real-world examples. For example, if you design a door well, you should never have to add labels that say "push" and "pull." If you want them to pull, put a handle; if you want them to push, put a flat plate. There's no way to do it wrong, and they don't even have to think about it.
This is a good goal: make things obvious. So obvious that it never occurs to the user to do the wrong thing. If there are four knobs on a stove, each one next to an eye, it's obvious that each knob controls the eye it's next to. If the knobs are in a straight line, all on the left side, you have to label them and the user has to stop and think. Bad design. Don't make them think.
Another principle: if the user does make a mistake, it should be very easy to undo. Google's image software, Picasa, is a good example. You can crop, recolor, and touch up your photos all you like, and if you ever change your mind - even a month later - you can undo your changes. Even if you explicitly save your changes, Picasa makes a backup. This frees up the user to play and explore, because you're not going to hurt anything.
I've found UI Patterns to be a useful reference for this sort of thing. It's arranged much like the classic GoF Design Patterns book, with each pattern description containing:
The problem the pattern solves
An example of the pattern in action
Sample use cases for the pattern
The solution to implement the pattern
Rationale for the solution
If you implement a search, make it a live search like what Locate32 and Google Suggest does now. I am so used to not pressing "Enter" at the search box now.
Well, one thing that may be obvious: don't change (even slightly) the position, color, font size, etc. of buttons, menus, links, etc. between screens if they do the same type of action.
Really good feedback is extremely important. Even simple things like making it obvious what can and cannot be clicked can be overlooked or too subtle. Feedback when something might happen in the background is great. In gmail, it's great that there's a status ribbon appearing at the top that let's you know if something is sending or loading, but it's even better that it lets you know that something has sent successfully or is still loading.
The "yellow fade" technique is something else made popular amongst the RoR crowd that accomplishes something similar. You never want the user to ask the question, "What just happened?" or "What will happen when I do this?".
Another trick that has become more popular lately that I've been using a lot is editing in place. Instead of having a view of some data with a separate "edit" screen (or skipping the view and only having an edit screen), it can often be more user friendly to have a nicely laid out view of some data and just click to edit parts of it. This technique is really only appropriate when reading the data happens more often than editing, and is not appropriate for serious data-entry.
If you are doing enterprise software, a lot of users will have small monitors at low resolution. Or if they are old they will have it at a low res so they can see giant buttons ( I have seen an 800x600 on a 24"ish monitor). I have an old 15" monitor at a low resolution (800 x 600) so i can see what the program will look likes in less than idle conditions every now and then. I know that enterprise users pretty much have to accept what they are given but if you design a winform that doesn't fit into an 800x600 screen, it's not helping anyone.
Try to think about your user's end goals first before deciding what individual tasks they would carry out when using your software. The book About Face has excellent discussions on this sort of thing and though quite long is very interesting and insightful. It's interesting to note how many of their suggestions about improving software design seem to used in google docs...
One other thing, keep your user interface as simple and clean as possible.
Here is a great DotNetRocks podcast episode where Mark Miller talks about how to create Good UI; Even though the show title is .NET rocks, this episode talks about a general rule of thumbs on how to create a UI to increase program user's productivity.
Here is an episode exerpt
Good user interface design can be done by sticking to some good rules and avoiding common mistakes. You don't need to be a latte-sippin tattoo-wearin macbook-carrying designer to create user interfaces that work.
I like to follow these 3 guidelines:
Standard - follow known standards/patterns, reuse ideas from all products you respect
Simple - keep your solutions simple and easy to change (if needed)
Elegant - use less to accomplish more
The best technique I found is to put your self in the users shoes. What would you like to see from the GUI and put that in front. This also gives you the ability to prioritize as those things should be done first then work from there.
To do this I try to find "layers of usefulness" and add / subtract from the layers until it seems clean. Basically to find the layers I make a list of all the functions the GUI needs to have, all the functions it should have, and all the functions it would be neat to have. Then I group those so that every thing has logical ordering and the groupings become the "layers". From the layers I then add the most important functionality (or what would be used for Day to Day operation) and that becomes the most prominent part, and I work things into the feature around those items.
One of the toughest things is navigation as you have so much to give the use how do you make it helpful and this is where the layers really help. It makes it easy to see how to layout menus, how other pieces interact, what pieces can be hidden, etc.
I have found the easiest way to do this is to start by see what and how your users function on a day to day basis this which will make it easier to get in their shoes (even better is to do their job for a few days). Then make some demonstrations and put them in front of users even if they are Paper Prototypes (there is a book on this process called Paper Prototyping by Carolyn Snyder). Then begin building it and put it in front of users as it is built often.
I will also recommended the book Designing Interfaces by Jenifer Tidwell published by O'Reilly
The items in the list you presented are really situation dependent - they will vary from application to application. Some applications will need a save button, some won't. Some conditions will warrant a modal dialog box, some won't.
My top rule for designing a usable interface: Follow existing UI conventions. Nothing confuses a user more than a UI that doesn't work like anything they've ever used. Lotus Notes has one of the worst user interfaces ever created, and it is almost entirely because they went against common UI conventions with just about everything that they did.
If you're questioning how you should design a certain piece of your UI, think of a few standard/well-known applications that provide similar functionality and see how they do it.
If your UI involves data entry or manipulation (typical of business apps) then I recommend affording your users the ability to act on sets of data items as much as possible. Also try to design in such a way that experienced users can interact with the UI in a very random, as opposed to sequential way (accelerator keys, hyperlinks, etc).
Sung Meister mentioned Mark Miller. You can find some of his blog posts regarding great UI on the Developer express blog. Here's a screencast of his Science of great UI presentation: part1 and part2. (both require Veoh player).
You can also find him on dnrTV: Science of great user experience: part1 and part2.
Here's a google techtalks about user experience by Jen Fitzpatrick.

When using a dropdown, the default dropdown height is usually too low (default is 8 items for winforms, for example).
Increasing it will either save the user a click if the number of items is low or make it easier to search the dropdown if there are a lot of items.
In fact, I see little point in not using all the available space !
This is so obvious to me now, but for example, it seems even VisualStudio designers haven't figured it out (btw, if you manually increase Intellisense's height, it will stay this way, but that's offtopic:))
I'll give one of my personal favorites: avoid dialog boxes at all costs. A truly good U I should almost never need to pop up a dialog box. Add them to your program only as a truly last resort.

The Coding Horror Blog regularly gives great ideas. Just some examples:
Exploratory and incremental learning
Self-documenting user interface
Incremental search of features/Smart keyboard access
Task-oriented design (ribbon instead of menus and toolbars)
Providing undo instead of constant confirmation
Another aspect: use scalable icons to solve the problem of multiple user screen resolutions without maintaining different resolution bitmaps.
