Just playing with it it feels great, one pony request: make it easier to just open a folder. When just trying out an editor I don't care to setup projects and whatnot, I just want the codebrowser to be rooted at some project dir on my system.
One feature that I really like in textmate is the "mate" binary they provide in Terminal. Before you launch your development server you can just type "mate ." and it'll open everything up for you.
I'm not sure if he's added it to ST2 yet, but in the original there was an option to open a directory as a project. If it's not in yet, it's probably on the to-do list.
