Here on my system, with configurations that have been converted from my MM3 install and ran through each MM4 build, I am unable to move the "Now Playing" node above the "Entire library" collection on the Media Tree page of the Options.I also notice that it seems to take a considerable amount of time to refresh the program after making changes to these options. The program locks up for ~8 seconds on my system which is a considerable increase over similar functionality in MM3. Making a change to the tree in MM3 happens pretty much instantaneously.Third is more of a comment based on my personal view of the new set-up of this area, rather than an "outright bug." I think it would be a good idea if there was a better distinction made between the hard-coded nodes, and collections. As it is now, it's difficult to tell what is what unless you select it and check of Edit and Delete is disabled. I think a visual indication as to whether it's a collection or not would be useful.
