VS.NET feature request: Browser Style Navigation Buttons

I love the bookmark feature in Visual Studio .NET. It really makes it easy to navigate within a single class file, but that convenience doesn’t extend to navigation between pages. So here’s my suggestion. Why not have browser style forward and backward buttons? For example, the back button would take you to the last activated line of the last file you were editing. It would seem like an easy to implement feature, and would save tons of time…for me at the very least ;).
