Very VERY cool Visual Studio plugin

It's not often that I come across a utility that impresses me so much that it literally blows my mind. Yes people, it's true, that today it happened to me... my mind was totally blown away by an idea so simple and yet so brilliant that it only took about 3 seconds to convince me that it is now the most important piece of my development environment. So much so that I see it as a complete game-changer, and it has me lamenting it's inability to be included in any of the other IDE's that I use.
