If I drag/drop and change the order, it gets reset if I add another item to the playlist (this was as of yesterday, don't know if they fixed it in today's release)

Haven't checked today. Glad they put OPML back

Edit: Just checked the ordering, it seems worse now. About 2-3 months ago (forgot when these features were broken), if I added an episode to a playlist, it will add it at the end of the playlist, the episode date didn't matter. Which I what I liked, as I can reorder the playlist however I want. Now I don't even know what order it is adding - it is no longer by date, neither is it at the end of the playlist.
