True, but this would still separate selection of predefined gradients/patterns 
and editing of them. But for users, the whole thing is just "define what the 
background/border looks like", only in different degrees of detail.

Exactly. That's what I meant by the description above: If the user chooses a 
gradient, the gradient editing mode is activated, if she chooses a pattern, 
the pattern mode is activated.

Not at the same time but depending on what is selected to be edited.

I'd suggest to show/hide the corresponding docker when the "mode" is switched.

Oh yes, I just saw. There is still some inconsistency in KOffice in general 
since Esc does not always return to selection mode. But here it does so that's 
fine.
