Script of the Day: Duplicate Playlist Folder as Playlist
Duplicate Playlist Folder as Playlist will copy all the tracks in a selected Playlist Folder to a new "plain" playlist, essentially duplicating the tracks as viewed when the Playlist Folder is selected.
Optionally, it can delete the selected source Playlist Folder and its contents (of course, the tracks remain in your library, but any playlists and sub-Playlist Folders it contains can be deleted).
More info and download is on this page.
