When I copy-paste a text in my Tinymce-editor with format (bold, underline, spans, divs, images, etc. etc.) now I first goto my Windows Notepad and paste and copy this text in my Notepad. So I've a clean text.

Now I'm searching for a programmer who can create a plugin that automatically cleanups all format like a same way. So when an user copy/paste a text (with the paste button in the menu, or with Ctrl-V or with drag-and-drop in the editor), the text must be automatically cleaned.
A solution is maybe by automatically convert through a old-school textarea without format?
