I'm making a project with the Nano Every and I wanted to use a prototype board to solder the components and make it permanent but I didn't like the simple protoboards so I'm making my own and I may also sell some. I wanted to ask your opinion and if you see any problem or suggestions before I order the PCBs. I have made two sizes.
I know that you want to save space but having the pin labels under the board will be inconvenient especially when probing a non working project with a meter or a scope looking for problems

I agree they are pointless there, but @reddragon9 has put the labels on the underside of the board also. Not highly convenient, but much better than no labels at all.
Are the power rails connecte to the nano? If not it's a bit inconvinient.
I would consider putting 5V & GND power rails between the rows of tri-pads. You can never have too many of those!
I would also consider placing the Nano closer to the edge of the board, so that if the board is placed inside a case, the USB socket can be available through a suitable cut-out in the case.
Speaking of cases, I would also consider the size of cases/project boxes commonly available on Amazon/eBay etc and design the boards to fit those. Many will have restrictions in the corners and mounting pillars in particular positions.
Hmm would it be fine to put the power rails next to the Tri-pads?
What is your concern about that?
Here is a design by Adafruit for a prototype boards which does exactly that: https://cdn-learn.adafruit.com/downloads/pdf/adafruit-proto-shield-arduino.pdf
Are these holes that I marked green - without metallization? - if yes, then why are they there at all?
