I would love a toggle/option to snap vector shape anchor points to any grid that I create on a frame. I saw my friend working at 6400% zoom for extreme precision and very precise geometric snapping. I was doing that as well, but I figured it would be easier at 100% zoom. At 6400% zoom, I have to use 0.1 stroke width and do a bunch of upscaling, etc.
Regardless: having the ability the make a grid on frames, and not be able to snap anchor points to that grid easily (and individually) seems like a missed opportunity to me.
