If you hate the default interface themes in Visual Studio 2012 as much as I do, you have another outlet to vent.
The UI designers have posted a survey where you can tell them how distracting and annoying you find the gray themes and black icons. You even get to comment on the (fixable) all-caps issue.
The UI people didn’t listen much to the (largely hostile) developer feedback during the product design – or more likely were constrained by some edict from on high - but seem more willing now to create decent themes for updates.
Here’s the Visual Studio 2012 Visual Theme survey URL
VS 2012 is a great product hampered by a lousy UI. If I could have a Visual Studio 2010 theme (with its coloured icons) I’d be more than satisfied with the 2012 release.
