This is idea to speed up mixing.
I don’t think any additional UI is needed. We can judge by ear, and if we want to see that, we can just show the mixer view.
Also, if the track scope could be focused on the track in the pattern editor view or mixer view when touched with the mouse, the Panning and volume sliders could be displayed. This alone would be a feature that would be useful if implemented.
I think the feel of the operation will be quite enjoyable.
What do you think?
