This is my KDE4 with two panels... I love it.
I have Archlinux + Kdemod Testing with this configuration:
1) Add this to your ~/.kde/share/config/plasma-appletsrc:
- Restart X
- Add a filewatcher plasmoid to panel with a blank text file. This plasmoid takes all the panel.Then you can add plasmoids were you want.
-Select the "show timezone" option of the digital clock for allowing it to be resized.
- Enjoy! (and sorry for my english)
