I think a cool thing would be an extra y key, something that I think would not be that hard to add, yet like the extra b key is something that a lot of people would appreciate, like when typing the word many, I am part of the people that type "y" with my left hand. Not a gamechanger to me, I still like this board and want to buy it when it goes live, but if there are other versions in progress, then something that bump it up against other alice style keybs
