*
* The #IdeEditorAddin interface provides a simplified interface for
* plugins that want to perform operations in, or extend, the editor
* surface.
*
* This differs from the #IdeWorkbenchAddin in that you are given access
* to the editor surface directly. This can be convenient if all you
* need to do is add panels or perform page tracking of the current
* focus page.
*
* Since: 3.32
