With the release of GNOME3 I would assume that people are interested in seeing how YaST2 (suggestion: rename it to YaST3 !!) is going to take form with GTK3. Of course this means eventually writing another application in GTK3, hopefully different from the old gnome-control-panel ‘style’ which was actually pretty confusion from the user point of view as it was far too close to gnome-control-center, thus confusing new comers.
My suggestion (unaware if it’s possible or not) was probably to explore GNOME3 features to serve YaST integrated already with GNOME3. This could be an interesting approach as it would offer integration and some advantages:
* Better integration with GNOME3 without having to write(/maintain another application;
* Take advantage of YaST2 modular structure;
* Present YaST in a prime space in GNOME3, thus offering a openSUSE differentiation point;
* No conflicts with possible KDE existing front-ends for YaST2;
* Improve users experience.
My proposal would be something like (maybe to be served as an extension for gnome-shell). Please neglect my ‘lame’ photo manipulation skills:
