For the way I work, I simulate a mono knob on my channels because that way I visually identify where I am, and I visualize the stereo channels in dual pan stereo channels like pro tools does. As your theme has proposed, use the stereo pan option instead of using the stereo balance/mono option or the default project (stereo balance) where only a central knob appears that can be configured on the right or to the left as it would with a mono channel. Obviously simulated, because we already know that reaper does not distinguish between mono and stereo tracks, but it would be good if we are using a protools theme, the mono tracks reflect the same visualization. For me it would be very nice if you could implement this option. I leave you a picture because if you don't quite understand, sometimes it's easier with a picture. He will tell me if this is possible and if he wants to make this change. Many thanks in advance
