Comment # 1 on bug 886906 from Martin Vidner

Regarding the TERMS, I understand a "pop-up window" as a subordinate window to
a main workflow, usually modal (preventing interaction elsewhere). In this
respect, the YaST modules are subordinate to the control center but they are
complex enough not to be called a pop-up. They are main windows.

Regarding whether we actually WANT to have only a single window for YaST, I
cannot really say. Lukas, any opinion?

Regarding the FEASIBILITY of implementing it, it is not trivial. The control
center and the rest are distinct programs implemented in different languages
and toolkits.

Some time ago (10 years) we used to have such an integration with the KDE
control center and decided to drop it, I forgot why.
