Am I missing something or does the 'Revert' option from the subversion bundle menu (ctrl-shift-A) doesn't display a confirmation dialog? I managed to crash TextMate as soon as I accidentally pressed that (it's right next to Update!!!) so I only lost my local changes in 2 of the 15 files I was working on... But honestly... no confirmation dialog? What's up with that?
(btw, I still think TextMate kicks *ss, don't get me wrong :)
