NiceVS
Make Visual Studio 2012 nicer
...But otherwise Visual Studio is still the best development environment in the Universe and it'd be pity to stop using it or stick with older version just because Microsoft employs color-blind designers.
The goal of this project is to bring nice 2010-era icons back and make Visual Studio more eye-pleasing, user friendly and productive. Icons are customizable. Other goals are to get rid of UPPER CASE menus and change icons of files affiliated with VS in Windows explorer.
