Just a minor thing that I resolved with stickers.
At night, with the very dim light of my studio, the brightness of the pads, and my current lack of memory muscle, I found myself trying to find the right knob in the 100% black 3x3 knob grid. The point of these stickers is only to locate these knobs, and the colors are irrelevant.
Maybe they wouldn’t be needed if there would be a setting to dim the light of the pads? Or maybe there is a business opportunity in 3D-printing colored knobs as well.
