@kevinmost i suggested to @edvin that we get a "flagship" tornadofx project out and that a macro keypad might be interesting. I do a little Arduino programming, but I've built TMK and QMK recently. We're mostly focused on a great front-end. What i've seen from HHKB UIs is spreadsheet-oriented and we were thinking a more intuitive UI with shareable keymaps would be useful and "real-world" for the project
