ctlr-o is the equivalent of ctrl-p in sublime or ctrl-t in textmate. It shows you the files available in your workspace. It used to tell you how to add files to your workspace when it was empty but that seems to have gotten nuked. [1] If you go to view->workspace you have a tree you can then fill in with folders and files. Click the folder button and off you go.
I'll add a menu item for opening a folder. [2]

Unfortunately this depends on whether the site tries to be clever and capture keys, though, there could just be a regular bug here. Will take a look.
> control-tab doesn't switch between tabs
Ah, I used chrome's default ctrl-shift-[ and ctrl-shift-]. Makes sense to add that one too though. [3]

If you press ctrl-enter or ctrl-shift-enter you have now evaled that file into that browser window. Any time you eval again, you'll be injecting code into that frame.

Can you tell me more about what's missing here? Are there specific menu items, etc? If you tried to use it just like Sublime (as in none of the other fancy stuff), what is harder/more difficult to wrap your head around?
