"Displays context-based TFS information about the currently loaded Solution/Projects including Branch and Workspace Supports Visual Studio 2010...
For those TFS users who frequently open multiple branches of the same code and need a visual indicator of which Branch and Workspace you are currently in, TFS Solution Info Tool Window will show you what you need at a glance.
Simple add-in but if you're in a bunch of different branches this will help you keep your context straight... I also like that he's going to release the source in a bit too. :)
