I've noticed there's no option in KiCad (bzr 6202) for a fill zone to have a thieving pattern. What's a good way to do this? I mainly want it reduce board warpage and perhaps strain. (Or more specifically, let the pattern help absorb up the strain from a large solid ground pour.) Setting a suitable grid size and manually clicking pads onto the F.Cu layer only (no mask)? If I do this, is there a way to easily hide them? Is there some clever way of managing them, for example by creating a component with 100 pads, no connected or visible pins, and a footprint that ONLY consists of a checkerboard of unlocked and unmasked pads? Then groups of pads could be moved around as needed.
