Regarding the HOLE situation:
The hole for reset access doesn't bother me. It's on the bottom and you should never see it once you've finished building.
Are these the same people who complain about a giant hole for dip switches? If a PCB has certain features then some accommodation should be made for them no matter how useful you subjectively think they'll be.
I am 100% in line with this opinion.
But please chillout guys, some don't want it, some don't care but no one desperately needs it. In case someone does, you can still open the case of course. Consider the hole to be gone completely, less work for the LASER.
Beware: if now others come at me screaming to bring back the hole, then I might change my mind about it again
Btw, yesterday I dealt with QMK, made a keymap and flashed it to the board.
This tutorial was very helpful. Guess what I used to flash: yes, I pressed that little button through the hole
