I have been testing a little bit.
So far I agree with everything JulianBus said.
And I would like to add that the spincontrol on basichome, is "buggish" when browsing fast.
I would also like to be able to turn off animations, and still see what's highlighted.
Currently you must have animations enabled.
In PM3 you had a progressbar always visible when playing music, I would like to see that on this skin also.
In filmstrip view, there is no need for a highlighted icon on the left side. Its just annoying, and takes up one space.
The skin Core, has this removed.
Besides from that: Great skin - I will have lots of fun with this in the coming days
EDIT: Mirk fixed one of the problems allready \o/
