Also, yeah obviously T can't be mapped, but I still put T in the same category as all the other square intersecting grid letters. There are other, obviously repeating groupings that would work better on a different segmented basis. Some examples: diagonals {Z N X Y A V K 7 4 W M}, circle based {O G C Q D}, loopy: {B P b d q J S 8 9 3 }, 7 seg: {L H T I F E}
