I stay by kde3 till kde 4 gets better.
On kde3 I have the possibility to add programs to the task-bar, how to do that on kde 4 I can't find out. When I drag a program icon down on the task bar, it is added, but by a reboot it's gone, even when I have set the session type on: restore last session.
The "widgets" (is this becoming windows?

) have less possibilities than the applets in 10.3. And the style and font (letter-type) is not mine, dolphin looks ugly and I don't see a way to change the style.
(Beside this I stay by 10.3 because 11.0 hangs after a while when I use opengl. (see my post in section hardware: Suse 11.0 hangs))
