1. The ability to use two panels on the bottom of the screen, one on
top of the other.

2. The "Run Command" plasma applet should be fixed up a little to
start working better as a panel applet.

3. A feature to make the panels gray instead of black.

Those would be very great. I haven't been able to duplicate the first
two together in any DE except KDE 3.
