I suppose this may be more of a question for add-on coders rather than K&M but I personally find TinyMCE and its buggyness infuriating, i.e.: - slow load of link/picture/media overlay - paste bold text, inability to un-bold it - paste link, try to type after pasted link, good luck! - etc. etc. etc . Every time I do anything other than just type there's a good chance something doesn't work right and by blood pressure will spike ultimately resulting in an aneurism and sudden death. I would like to avoid that, and I never ever had any issues with YUI. It's snappy, it just works, and doesn't have all the infuriating "features" of TinyMCE. So my question is, how difficult would it be to just rip this POS TinyMCE out of Xenforo and replace it with YUI?
