QuickForm - HTML Textarea

Has anybody extended QuickForm to include an WYSIWYG HTML textarea? Just wondering if somebody is working on it, or if there is another way that would be preferred. I would imagine it would mean creating a new HTML QUICKFORM ELEMENT TYPE or at least extending the existing one. I can't imagine nobody else hasn't had the need to use something similar, for clients used to using Rich Text style editors (like MS Word etc.) Interested to know. Stefan F.
