I started writing the same thing, and thought I'd just add onto this instead. Tried using Vim because I like the look of how flexible it is to tile windows, but I just cannot move away from Sublime's file search.

I don't even click tabs that I have open any more, I just hit Apple + p and start typing say g-l-o for global.css and I know its there, hit enter and voila.

Like you say, multi-platform too, so I get to use it on my little Ubuntu netbook and on my iMac. Love it. Really should buy a licence.
