1. Since I still can’t do sorted queries, I don’t want to populate the song list with your entire library, because that would take ages. However, if you choose all albums manually you can force this behaviour. (a limitation of FireFly)
2. Queries are not implemented on static playlists yet. (a limitation of FireFly)
3. Stupid programmers mistake. Even if a queue is defined, I use what’s showing in the songs list as queue. Will be corrected soon!
