How do I add additional plugins to my already existing CKEditor? - ckeditor

Question

This link https://docs.ckeditor.com/#!/guide/dev_example_setups strongly encourages use of the CKEditor builder in order to manage plugins, and strongly discourages installing plugins manually.
Manual Download and Installation of Additional Plugins (Not Recommended)
Although at a first glance it looks like the simplest way
of adding plugins to CKEditor, it is not only inefficient but also may
result in a headache when trying to add plugin A, that requires plugin
B, that requires plugin C (...and so on).
In a brief summary it involves the following steps:
Downloading the predefined package (Basic/Standard/Full) from the
Download page.
Downloading additional plugins manually from the
Add-ons Repository.
Downloading plugins required by additional plugins
manually.
Enabling additional plugins manually through
CKEDITOR.config.extraPlugins.
Then it tauts its Builder:
Using Builder (Recommended)
Using Builder to build a bundle with all required plugins is highly recommended in case of using customized
packages, especially those with additional third-party plugins.
Refer to the Installing Plugins – Online Builder Installation article
for information about building a custom editor package.
But in visiting the page for Builder, unless I'm missing something, it only builds a completely brand new CKEditor from scratch. I can't find any way to keep my current configuration and add plugins.
If there is literally no way to add existing plugins except by doing it manually, I find the language in the docs strongly discouraging this very strange (since 99.9% of the time I'll want to add plugins on the fly and not at the very beginning).
So is manually adding plugins the way to go if I already have other stuff set up?

Answer 1

Most crucial point to keep up with builder is to keep your CKEditor up-to-date. Imaging pain of updating all plugins manually.
Just build our base CKEditor - with ckeditor itself and plugins which 100% you will use in your project.
But no one stops you from adding your own or community plugins. You just need to configure and keep config.js in your ckeditor folder. so you will have your extra plugin configured on each ckeditor update.
