Completely customizable backlighting on a mechanical keyboard and able to save in a profile. Say, for instance, I have one game that uses 12 keys. I'd like to set those keys as the only ones lit. I have another game that uses 7 keys. I'd like to set those keys as the only ones lit. Or, as an alternative, a different colored light, say red for the main keys and white, or maybe green, for the gaming keys. It would have to be two colors that are really opposite.
