Once an mdi child is maximized, all mdi children are maximized. This is not always desirable, and the solution is to "fake" maximize the MDI child windows. Today we'll begin to template that, plus add a feature where the caption is removed so the fake maximized window can't be moved (and will appear "docked"). Also, as a bonus, we want to add tabs to the top for switching between fake maximized mdi child windows! And we're winging the whole thing!
