I've noticed that even though I can create guides at half-pixels (eg. one at 5.5px and another at 10.5px), snapping to them is proving difficult. I went into the preferences and tried to change the Snap to Zone option to .5px but ID will only accept whole numbers from 1 to 36.
Does anyone know if I'm able to tweak this to accept half-pixels? Or maybe there's another solution. Thanks!
