Ive cleaned up the gradients and fonts for the min_x2 skins, Neutron_x2 and WMP10_x2 are next. I can also do this fairly easily for any other skins for XMPlay where the source is available and the author permits.
Were the other skins ever finished?
I hate to keep people waiting so here is another update
Min and Neutron are nearly done, please point out anything I might have missed or could be improved. I have to improve wmp10_x2 still.
