Almost in every application, i have need in wysiwyg editor for content.
In most of them I have used tinymce extension writen by MetaYii(with some ugly changes, added by me, to connect elFinder file manager to it).
Recently I have written my own widget for TinyMce and for elFinder with possibility of integrating them. Also I have written separate actions for TinyMce compessor and for spellchecker plugin. So i think that my code looks more cleaner than something like tinymceelfinder extension, that has similar functionality.
Also I have added less ugly skin for tinyMce(modified version of cirkuitSkin).
