I'm asking the following questions just for curiosity/gaining experience not 
that I'm insisting on the current code seen that the proper solution is still 
being discussed in this thread.

Converting the OSD widget to Plasma::Dialog was trivial *but* even if i set 
WindowStaysOnTop, the OSD still stays behind of focused windows. When this was 
a QWidget it was always on top. What's the trick in here?

I couldn't find a way, an example of using scalable icons instead of png ones. 
Should this be manipulated manually like appending an .svg(z) extension and 
searching for an svg and fallbacking to png if not present?

BTW: How long api.kde.org will stay unreachable? That's bad :(

Thanks
