GitHub Header Implementation Switcher

I made a Google Chrome Extension for switching between header files and source/implementation files (for iOS: .h and .m, but also works with .mm, .c, and .cpp files) on GitHub.com using the keyboard shortcut Ctrl+Cmd+Up, like in Xcode. You can get the source here.

In Chrome, go to chrome://extensions, press "Load unpacked extension...", then select the folder to get it running. If I have time one day I'll package it for the Chrome store.

It's pretty simple. I'm not a Javascript guy so the code might not be perfect but it's quite useful.
