- The ability to use two panels on the bottom of the screen, one on
top of the other.
Filed it. Please add a screenshot of your KDE 3 setup to bolster the bug a bit: https://bugs.kde.org/show_bug.cgi?id=190472
- The "Run Command" plasma applet should be fixed up a little to
start working better as a panel applet.
Please be a lot more specific. Assume that I have no idea what you are talking about :) You can send me a screenshot if it helps.
- A feature to make the panels gray instead of black.
You can change the theme to a different colour. In fact, the panels have not been black since KDE 4.0.
