Somewhat un-planned, I spent the afternoon getting familiar with the latest Mozilla release and lo and behold, I kinda like it. At least enough to make the tweaks necessary to build in support for it in Blogger Pro. It wasn't too hard. And it's not the half-assed non-IE support that's in free Blogger, either. It's dang-near equivalent to the IE version (screenshot). The only things I didn't get accomplished were the formatting buttons (bold, italic, href) and keyboard shortcuts in the editing form (which are also missing for Mac IE). If someone wants to tell me how to do that, that'd be great. (BTW, there's even spellcheck in the Mozilla/Mac version, which doesn't work with IE/Mac.)
