I personally see a lot of potential for the button that toggles the “move up and down” buttons, it could essentially become a secondary function button.
Ideally for example it could act as :
toggle that button and bottom row becomes mutes (or solo, decide which you prefer/need in the M4L module) instead of stop.
toggle that button and columns become volume instead of clips (decide for the rapidity of the volume decrease increase in the M4L module)
These are all simple stuff but it would make a huge difference. Anyway, I’m nowhere near having the skills or time to code that so it’s really wishful thinking at this point.
