Go Back Visual Studio Add-in
[Via .Avery Blog]
The Go Back Add-in provides a Navigate Backward functionality that is different than the normal Navigate Backward functionality. (Which does some neat things like close a file if you happened to have opened it while navigating forward) The author of the tool is pretty passionate about what he wants and built the exact functionality he was looking for, if you agree with what he likes then you should love it.

This is a pretty cool extension to the Navigate backwards command in VS. Oh, if you like that command in general then you might also want to check out the VSMouseBindings powertoy that will let you bind the navigate back/forward commands to your extra mouse keys. Josh
