Hey,
I didn't use the browse, yet, because my freehoster doesn't allow sockets() (in 2010, they are available). So I don't know, if it's included, yet.
Can you include a browser for files which are changed? Sounds funny, so I explain: MaNGOS (WoW emulator) codes in C++, via GITHUB you can "look into" the file and you can see which lines have been changed. This should be available for PHP, C#, C++, JAVA, etc. files.
