I can't seem to find how rto change the background color of the system tray. Can anyone point me in the right direction?
Also, how do you change the appearence of the tackbar? (minimized apps)
I am not sure this is what u want but,
right click on the kicker panel->"Configure panel" and then checkout options in there for "Layout->Appearance" and "Taskbar"
you can put background images on the buttons, but you cannot change the background colour of the kicker unless you change the colour scheme you use. The other option is to make a small 1x1 pixel image of the colour you want and set it as a background image.
