Glad you enjoyed them! Photos of both populated boards, both sides, should be available on the repos (if not embedded on the main README, check the Images/ folder).
I won't be sharing the schematics, though if you have any specific questions about something, I can try to answer as best I can.
RE: LCD bias - I mentioned in my AGZ writeup that the stock bias voltages aren't required when using the IPS displays, this also applies to the CGZ. This is because the LCD kits that I use have all the bias voltage circuitry built-in on their flex PCB adaptors, so I only needed to supply 3.3V/5V from my boards.
RE: Debounce circuit - Since the stock power switches carry the full system current, they can cause issues when they bounce due to dirty switch contacts. I redesigned the power switch circuit to instead use a high-side load switch implemented using a PFET with an RC time constant for debouncing.
