There should be a DJ mode. When you’re DJ’ing with Roon, 100% never stop a song mid track.
Make things easy to modify the queue, where you need to punch someone in the face to stop a track. The default for everything is only modifying the Queue.
So here I am, playing a song, and there isn’t a Queue option ANYWHERE.
I’d like to see Roon expand into this DJ mode. I (hope!?) that skipping a track mid-way is a cardinal no-no. Then between tracks you could MAYBE beat match. But it’s a faaaaaar backseat to simply playing a queue and NOT accidentally clicking on a Track and hijacking what’s playing.
You should post this in Feedback > Feature Suggestions and I think it could do with a better description of what you want because I, at least, am not following.
If adding to queue is what you typically wish to do (as I do) that’s a cumbersome process to repeat each time, however, it can be streamlined as one can change Roon’s default click actions.
Roon → Settings → Play Actions
I have my system configured to queue, so it doesn’t disrupt what’s already playing.
Here’s an example screenshot… where I have moved “Queue” to be at the top of list (so it becomes the default action).
