I don't understand the surrounding decisions. Differentiating by wired/wireless makes sense. Using two different programming systems? No. ZMK instead of adding BT support to QMK? Why? RGB underglow but not individually programmable key backlights? For the money they are charging, all of these things should have been extremely easy decisions. Anyone have insight?
The go to for the ErgoMechKeyboards realm seems to be to use ZMK for these sorts of things. Power consumption and customization of certain things is better supported. Individually programmable key backlights is nice, but imo a gimmick. That being said I never use backlights on a laptop keyboard, or mech keyboard, so I don't know what the use case for wanting ur Q to light up in a colour different to your W key would…
You generally don't want Q to light up different from W, but you might want to have a low-level green glow by default and slightly brighter colors to distinguish keys around the periphery.
