I downloaded a playlist on Plexamp and for some reason the order of the songs is different. There is no option to reorder the songs by title, year etc. Same thing for grouping tracks by artist or album, which are available options when streaming the playlist! Also, being able to duplicate smart playlists to edit one of them quickly would be very appreciated.
I had this happen to both of my android devices, I haven’t had the chance to test this in iOS. It is particularly annoying because for extremely long playlists it essentially forces you to shuffle through the songs. The smart playlist duplication should really be implemented in Plex in general, as it would come in handy for the server as a whole and not just Plexamp.
