Thanks to both!
It sounds promising!
It's sounding like, with panel reintroduction, a special skin may not even be needed to get the spirit of MM4.
Just put it on the right view and customize the panels.
I like the variety of different views you can get with MM5 and that's great for fun-time, pure listening mode.
But editing, organizing is, of course, different. Although, I'm not all that crazy about how the tree is laid out.
Maybe a skin would help with that.
