This is great! I got the basic config working in just a couple of minutes. I have never had WYSIWYG editing because, well, because using MSIE sucks and I don't need no stinkin' WYSIWYG ;-)
But seriously, this is way cool. My users are going to love it. I do see the speed issues though, and I'm going to need some help getting the conditional macros in place for optimization, but this is a great feature. (But I don't know if I can bring myself to add Smileys.)
