I’ve got the same Atreus. When I got it I realized the potential to move the keys around so a quick search led me to minimak. On realizing that just moving 4 or 6 keys could make such a huge difference because of how bad QWERTY really is….

That got me down the rabbit hole of layouts and I too settled on Coleman-DH. I still haven’t gotten entirely back up to speed, and I still make frequent mistakes. It was bad / hard enough that I actually gave up a few weeks ago and switched back to QWERTY; however it was so bad to type that way again that I switched back to Colemak-DH and it has been much easier the 2nd time.
