Earlier quoted context omitted.
I use a custom built corne keyboard which staggers the columns based on finger length, but not the rows. I don’t think I will ever go back to a standard layout keyboard after having used this for a few months. https://imgur.com/a/kEEIRhf to help visualize.
Cool, how'd you get started? Something like this still accurate? https://www.reddit.com/r/crkbd/comments/esv3i8/guide_corne_d...
If you won't like to source all the components yourself there are vendors who happy to sell you kits, but you can make 3-5 keyboards for that amount of money.
I suggest to use the Miryoku[1] layout.
