I got a ZSA Voyager split keyboard and then spent weeks exploring custom layouts. The first question was QWERTY vs something better. Then there was layers and layer navigation. And should I swap out the key switches? And Keyboard Maestro.

Now I'm trying to abandon 30 years of muscle memory and typing at 4 wpm while I learn Colemak-DH. Maybe what I should really do is build a custom 34-key board...
