Hi Sergio,
Playlists automatically “Play from Here”, in contrast to Albums. See the Play Options page in the User Guide. I’m not sure how you might Queue a single track from a playlist. Anyone know ?
You can move back in the Queue using the transport rewind control. If you want to review what played then History is the place to look. You can select songs from History and make a Playlist if you want to preserve an inspired Queue.
There’s a thread in Feature Request about Queue behaviour. The current implementation was adopted in Roon after extensive discussion of the alternative, which was implemented in Sooloos.
