Hi, I've been designing a keyboard pcb, and I'm a bit confused about GND and no net zones, as in when I should use them( both layers, or just one? Also, should I have isolated copper fills at all?). Also, I'm running into the issue where the option for duplicating zones, merging zones, adding a zone cutout and adding a similar zone is mysteriously grayed out, does anyone have insight into why this may be?
