I agree: ship it. The animations look very nice and I don't notice any real \
performance issues, and I have pretty old hardware. Of course the CPU usage \
goes up a bit during animation, but that happens on most animations in \
plasma, and isn't really an issue imo. Codewise it looks good as well, but \
I'm quite new to plasma development myself so that doesn't really say that \
much.
