...although this isn't a major interface update, and I'm sure somebody else had it before.
In the next ver of a certain product, every dockable interface component also can be set to pop out and hide itself, based on mouse activity. So, you get an almost full-screen editor combined with almost every tool you need being very quickly accessible.
Quite nice. It's much easier to work with than Visual Studio 6 ever was.
Now just don't get me started on system requirements...
