If you want even better ergonomics, add tenting, concavity, and move the modifier keys + return/backspace to the thumb cluster (which should be shaped and angled so you're not moving your thumb laterally to hit it). The Dactyl-Manuform[1] is a good example of these things. [1] https://github.com/tshort/dactyl-keyboard https://github.com/tshort/dactyl-keyboard
