We should use KConfig/XT for filters ? With that, we can easily uses a widget 
made inside QT/Designer, as KConfigXT associates the field of a widget with a 
KConfig object.

I think it's better to have this in the KisPreviewWidget, tonight or tomorow, 
I will make a "mockup" of a new KisPreviewWidget to show you my ideas on the 
subject.
