Worked on finalizing the PCB for manufacture, turns out I have more problems than I thought so lets go through them:

Removed the charging option for ports:

• USB port on laptop can not provide the power needed to enable charging for all 4 ports.
• If I wanted charging made available I will have to connect the USB-C ports CC pins to the MCUs PD pins (yes the STM32G0B1KBTR MCU I picked can handle direct connection with diff pairs and PD)
• But even if PD connected (which allows the port to draw more power) the USB port on the laptop still can not provide enough power to since most laptop ports provide 500mA –> 900mA while charging option requires 1.5A.

Added test points:

• Bro its £70 (Manufacturing and shipping) therefore if something goes wrong I would like to give myself a higher/easier chance of finding what is wrong with the board.
• Test points enable me to physically debug the board with a volt meter etc, aaaaa frick i just remembered, I need to add GND test points as references… crap would have been bad if I forgot to add those cause that would make my test points redundant…

Fixing DRC errors:

• Man so many DRC errors since I was moving stuff around some vias accidentally joined up with traces running below them, but all those are fixed now, should be fine.
