The waiting list (actually the cache) can hold 3000 to 6000 tracks, depending on the model. My library of albums on the internal SSD is organized in different folders with different albums. When I display one of these folder in the library I can either select albums one by one to add to the waiting list or choose ‘play random’. That saves the trouble of having to choose albums. With this last option the cache is filled up to the brim with random tracks from that folder.

It would be nice to be able to have a user definable number to add, say 100, tracks. So from another folder I can add 200 more and from yet another 200, and even add a qubuz playlist on top of that.

It is not doable to select a 1000 or more albums manually to fill the waiting list.

Just a thought. I hope you understand what I mean.
