SHANKS I have reviewed your suggestion. The Rich Text extension completely replaces the default editor, using a different architecture. It does not rely on a textarea, does not expose DOM-based text selection, and does not support direct BBCode insertion. Therefore, compatibility is not possible.
However, I noticed that on your forum text selection does not work when switching back to the default editor using the toggle button. On my test forum, after switching to the standard editor via the button, the extension works as expected
