Switched to Atom, never looked back.
I'm gonna be that guy, but: I'm surprised how much I like Vim. Y'all should give it a shot sometime.
For background — I'm using Square's Maximum Awesome setup, with a few minor modification.
I love Setups. Every time i read one, there is something new to learn.
This time it was: ALT + CMD + ARROW LEFT/RIGHT to switch between tabs. Now this is going to be a fun day.
In case you weren't familiar with the shortcut, this works in most web browsers too!
