Developing Rails apps on OS X and TextMate is an incredibly enjoyable experience, but one thing I've really missed from my Windows days is TortoiseSVN. I know there's a ton of OSX subversion GUI clients out there, but none have really done it for me. So when Jeff pointed me at SVNMate, a TextMate plugin by CiarÃ¡n Walsh that gives you a TortoiseSVN-like interface in the TextMate drawer, I was all over it. It's not perfect, but damn close. If you're in the same boat as me, I'd definitely recommend giving it a go.
