I'm wanting to add descriptions to folders for use in playlist headers. Between the track and album count, duration, header, and icon, the functionality of the playlist header is largely same for folders as it is in playlists, ie:
It might be worth adding a settings panel for folders in their individual context menus with similar options as playlists
(name, view - which you can already set for folders via the program header, and description).
Not a deal breaker obviously, it's a veeeery minor wish, so all good if not!
