Here's a bit of deep Moom lore.

For a 21:9 screen, the max grid size of 25 isn't good enough for me, I specifically wanted 36 so that I could make three 'panels' at 11-13-11 resolution.

Found out with a bit of emailing back and forth that you can by pasting this into a terminal:

    defaults write com.manytricks.Moom "Grid: Maximum Dimension Size" -int 36

The grid display ends up being a bit small but I only tinkered with it for long enough to make 1,2,3 assign to the grids, 4 and 5 assign to the left-and-middle and right-and-middle, and q w e, a s d, z x c to top-middle-bottom of each of the three panels.
