Or better yet, adjust the spacing so it could mabe a propper 3x3

Spacing got improved in the last update, it's pretty easy to do 3x3 with the rectangular grid and 3x4 with the hex grid. Spacing is now consistent across tiles (note on why that was tricky below). It also automatically disables the till grid when you're using Snapping Tills, although I recommend giving the till grid a try, I think it's more flexible than Snapping Tills (especially if you use Snap Grid Key). For example you can do tileable 4x3 spacing, which Snapping Tills doesn't have a good solution for.

Why this was tricky: spacing was hard because the code uses 1.25 as the spacing, but tiles are 4x4, so this doesn't divide evenly. Optimal spacing is actually just a tiny bit above 1.25, because if it's exactly 1.25 then the soil conflicts. When I initially updated this I didn't have a full grasp of the farming mechanics and thought optimal spacing was the most important, but now I understand that there's a lot of tile-based stuff happening, and in most cases 3x3 is better than 4x4. So I changed it to be 4/3 to evenly divide into tiles.

Added the till option as well now
