You can even define configurations for different systems/hosts/users from a single place. I’ev atomized my config and I can reuse lots of parts for my different machines. Also my user config is nearly identical (except hardware specific things).

nix-collect-garbage I configured it to run every 7 days.

I do use a Dvorak_ES layout and it works perfectly fine in both Sway and Hyprland. I assume Colemark would too.

But that is to be expected when switching stuff.
