For those of you confused about the lighting sources. There has been a few improvements:
1. 4XRGB on ESC stays as is, it uses the same channel as underglow
2. Underglow increased from 1 row of 8 to two rows of 7 each (14 total)
3. The light strip diffuser part, 3 hotswap LEDs will be separately controllable (from underglow) as you activate/deactivate a backlighting layer. So you will be able to turn the light on and off without pushing the capslock key. In the prototype, it is a indicator light but I realized how little I actually use capslock. Never used other indicator keys.
