Great to see this, thanks for sharing! Do you have plans to make it available in nixpkgs and potentially as a home-manager or nix-darwin module? Then I could add it to my config and have everything set up automatically.
I don't use nixpkgs personally but would love to give it a shot, check the repo in a day or two to give me some time to learn to ropes! I'll shoot you an email if I need any help :)
The first question that came to mind for me is “is this already achievable with Nix-Darwin”? If not, it fits very well into the nix ecosystem
