I prefer fully split keyboards overall, but every time I go back to using my Atreus I'm reminded what a nice keyboard it is, and how lovely it feels to type on it. Those guys know what they're doing.
Most things are stock. I had to move the ; and ‘ keys because of the Colemak Layout. And I moved/added a couple of symbols to the second layer also because of Colemak. Other than that most things are exactly the same as how it comes.
