Sublime Text 2 is a great code editor. I've been using it for over a year as my default editor after moving on from EditPlus2. It's fast and features a great file overview sidebar, file tabbing, project saving and a customisable colour interface.
After an unsuccessful attempt at installing SublimeLinter months ago, I decided to give it another go. SublimeLinter is a syntax checker package for SublimeText and allows for auto syntax checking.
