Comment 2 for bug 720424

I see how it's natural to want to do this. The one gotcha for me is that
the panel is also hosting the menu of the app which is in the
foreground. So it's arguably as much part of that app, as the top
maximised one.

I *think* we can implement what you want and have that "just work". It
may be just fine that way, or it may need to be re-thought after some
testing.

So let's call this a design +1 with room to reconsider in Natty+1.
