Excitingly, my package get merged into sublime package community list last weekend. And within a week, I got a pull request from Carl Furrow. Carl says it is the beauty of the open source. Anyway, it does make me feel so social in the bits and bytes world ;)
This package is totally inspired by Visual Studio Web Essential, which has a awesome code preview window for CoffeeScript, TypeScript etc. I really like feedback it provides as I am writing the code. So I ended up with this package provide similar code preview tool for Sublime Text.
The source code is hosted on github, feel free to contribute new features to the project!
