"a bit too much" in the sense of "too heavy on the eyes" or in the sense 
of "most computers can't do this"? I'm assuming you mean the latter since I 
think the animation is really subtle.

What I'm trying to do is just to add a bit movement on the right so the user 
notices that something changed when he clicked on the left. And I didn't want 
to do it with a blinking red rectangle. :-P I tried to connect left and right 
but apparently failed (I only got negative feedback for the screen capture I 
did of that animation). I don't know how to do the slide effect without > 50% 
of the KCM code just doing that animation (which would be a third kind of "a 
bit too much").

I'm open for good ideas...
