It would be nice to have the x,y axis and border there without the squares; like "grid -1"* or something. I honestly don't use the grid that often (if not only for little tiny things and gimmicks requiring symmetry), so this would be a useful thing to have.
*grid 0 would make the most sense, but it would require that there be five levels, and the four original levels be bumped up by one
