I heard about sublime text 2 months before. Everyone said it is great. But I didn't give it a try because I think it is just another editor. Yesterday while I was trying to learn python by following Learn Python The Hard Way, I decided to use it and found out it does work great. Here are some useful packages/plugin I liked very much.
Sublime Package Control The first package you should install. It is a package manager which allows you install/remove packages.
Theme - Soda Popular theme. It can be install though package control.
alternative_autocompletion Textmate like autocompletion. t can be install though package control.
SublimeRope Python autocompletion. t can be install though package control.
SublimePythonTidy Python code formatter. Installing it though package control doesn't work. Read the instrution in here to install it manually.
