After I thought there would be only this white skin I found now by chance the other skins. They are really well hidden.
I like the "Dark Side" Skin from XMM7 but can't find one which is like this one in XMM8. There is a skin which is nearly like it but different in view pounts which makes it not really nice to look at. If there are some windows open like web import I have still some white fields on it.
