ipkg install ncurses
Sorry — my bad, I’ll add that to the deps for the package.
As far as the other style playlists, those are gone for good. It will be sql playlists from here out. As far as a timeline, I’m not sure. It will probably be some time. I might throw together a web page that will convert a .playlist file to a .sql script that you can run on your database though. that might be a reasonably stopgap.
I’ll post back to this thread when I have something.
