Add colors to tabs based on pinned-state, different projects or your own look and feel
Since the new Visual Studio has a lot less color, I don't mind BUT my tabs look all the same and miss some visual structure.
Maybe it would be nice to assign you own colors to your tabs, different colors for pinned & not pinned- states or different colors for each project!

This was available with Productivity Power Tools 2012, but I am missing it in VS 2013...
Color per file type and color per project would both be nice.
