Add ckeditor custom plugin

[allphat]

Is it possible to add a custom plugin?

I can't find a method to load my custom plugin.

I defined my plugin using the ckeditor documentation and stored it in a directory.

I can't find a way to tell ckeditor to get my plugin from this directory.

It should be possible with access to current CKEDITOR instance. Is there a way to access it?
