OK, time for something about consistency.
In the mini mode / main windows you have the 3 top right buttons to do minimize, extended playlist, close
In the extended playlist windows you have the 3 top right buttons to do -greyed out-, auto size, close
It would be more consistent to not have the "middle" button in the mini / main window do the extended playlist, but be -greyed out-, the same as the other window.
And at this point, you could even think of just keeping 2 buttons per window, only the ones that re actually doing stuff - but Iguess this would change the feel of the skin a lot.
(you'd need to move the timers too)
What do you think?
PS: I think Matte is my version of choice now, so thanks for it too.
