So I'm trying out some new software (like usual): Coda. It bills itself as one window web development. Sounds nice as I'm usually bouncing between Finder, an FTP client (Transmit, by the same people as Coda), CSSedit, TextMate, Photoshop, Safari for my CMS backend, and then Firefox for testing and Firebugging. So, Coda basically covers all the things I need to do (except Photoshop, which I wouldn't want to switch away from anyway, and Firefox/firebug).

I'm liking it so far (I'm 4 days into using it exclusively) mainly cause I can get in "project mode" and stay focused by paying attention to only one window.
