The nugs mobile app's queue functionality lets you personalize your playback queue, with options to organize and sort as you please. This feature also unlocks the ‘History’ of recently played tracks.
After starting playback navigate to another recording and click the 3-dots next to a song. Click 'Play Next' to add the song to your queue immediately after the song you're streaming, or 'Play Last' to add to the end of the show/playlist you're streaming.
To see your Queue expand the player to full screen and click the queue button in the bottom right.
Scroll up to see a recent history of played songs or use the handles to re-organize your queue.
