I had some playlists (created within Amarok, i.e. not from .m3u files or similar) arranged into folders. After upgrading to 2.3.0 I seem to have lost that folder structure: the playlists are still there under "Internal Database", but the folders are gone.

Anyone know if I can get 'em back? And if not, any devs want to comment on whether this is still an area undergoing active development? I'm not keen to start reworking that organisation if the next update is going to blitz it again.
