Thanks!

I’d totally be up for adding accepting a PR for an alternative layout based on those design choices if you’d like. I’ll try to have a guide for how to do that within the next day or so, people are asking for this to add other languages.

4- This is the most radical suggestion, but I believe a even number of columns is better than odd. Because the middle column might be confusing sometimes for some users as they have to choose which finger to use to press the keys in there, which would not happen with a 4x3 grid.

I actually tested a 4 column layout in multi-ling-o, because I thought it could be useful (then you would need very few swipes). Boy was I wrong… it increased the hunting-and-pecking factor by a lot, and was so much more difficult. There’s something psychologically natural-feeling about the 3x3 grid with a center hub-key, that makes things much faster.

I have built the code in a way that makes more columns possible tho.
