Here is how the re-ordering tool works:

"Playlist re-ordering tool implemented. Select a playlist (or hierarchy of
playlists), then choose Ordering from the Tools menu. The selected playlist
and its descendants will be reordered such that playlists occur first (and
are sorted by title), and tunes are then sorted by track number."

I only need something like this when I have a bunch of loose tracks in with some playlists, so sorting by track number doesn't help. I'd like to be able to sort the playlists up top and then sort tunes by title...

Just a wish.
