but I'd like to suggest, for a future update after 3.0, if any USER queued tracks (via Queue Next) exist when turning on Auto DJ, those queued tracks should remain in the list of tracks to play and Auto DJ tracks should be added AFTER them, OR....
that should already be the case now and just retested to confirm. Can you give me step-by-step what actions you are doing?
Scenario A - Just start Auto DJ and the Now Playing list is cleared (except for current track) and populated by AutoDJ selections. Turn off AutoDJ, then start it and process repeats.
Scenario B - AutoDJ & Shuffle are off. I delete everything in Now Playing (manually-Del key) except for current track. Use context menu Queue Next to add to Now Playing list. Start AutoDJ and same as Scenario A.
Scenario C - same as Scenario B except Shuffle is ON. When AutoDJ is started the queued tracks remain in place and AutoDJ adds to the list to achieve the list size.
(Shuffle has 3 icons. There's the one that looks like "Equal" sign (No Shuffle), then "Equal" with "backslash" kinda (Shuffle) and then the 3rd one. What is the 3rd shuffle icon?)
Scenario D - AutoDJ is OFF and Shuffle is ON. The list generated by AutoDJ is there but I don't manually queue any tracks. I manually delete most but not all in the list. Start AutoDJ and the list is cleared except for the current track and populated from AutoDJ.
I hope that helps.
