I just built this Ergodone over the weekend to replace the JJ40 Planck that I use at work. I really needed the number / symbol row, since I still have trouble remembering where the symbols are even after using the Planck for two years.
I actually use the Colemak layout, but I leave the keycaps as qwerty, since admin level powershell only likes qwerty, and some of the remote servers I go into don’t retain my keyboard settings. Then I can just look down and see where the keys are.
Good luck!
