Yes. It is ok. Running smoothly.
Well, to be honest, maybe a QGV is an overkill for kreversi and simple 
QPainter-based implementation will do, but oh well, I'm learning new 
technology and it seems to do what I want and the coding process is 
straightforward. Performance is good, coding is enjoyable, what else 
needed? :)

Yes, I hope. You provided quite a useful piece of feedback IMO.

Uh. I can imaging how BIG will be that change to KGoldrunner :).

Let's hope it will :).
