In the screenshot you can see Kicker (top edge of the picture) and at the bottom you can see a "dependend control-bar" (Abhaengige Kontrollleiste) of kicker.
I posted this as KDE-Improvement (not as screenshot) because it is a kind of request to the developer to remove the white-border in the kicker-panel (top edge of the picture) so that it looks as beautiful as its child-panel, and because people can improve the look of KDE 3.3.x already now if they:
1. add a dependend control-bar to kicker,
2. remove all usual applets from the kicker,
3. minimize kicker as needed.
p.s.: i am using Taskbar V2 and Systray V2 (both hopefully integrated in KDE 3.4 , click on my username and you'll find more about it)
