I love the fact that Visual Studio 2005 comes with a class designer. Unfortunately, as with most v1 products and features, it's quite lacking. One feature it needs is the ability to display show what interfaces a class implements and vice-versa. From any class, you can see its base class or derived classes. From any interface, you can see its base interface or interfaces. Why can't you see a classes implemented interfaces or an interface's derived classes? This just doesn't make sense to me and I hope it gets added into the next release. I haven't played with it, yet, but this is a seemingly small feature that should be included, one might think.
