- upon installation, app will install NixOS on the user MacOS. Just like in this video: https://www.youtube.com/watch?v=Z8BL8mdzWHI&t=12s
- the app will show the process of NixOS installation
- then, the app will live as an icon in menubar with options "Settings" and "Quit"
- When clicking on settings, window will open with tabs "General" and "Packages"
- Nothing yet in General as content
- In packages, you will see all packages installed in your nix with buttons to uninstall (remove from flake file and "darwin-rebuild switch --flake ~/MacNix#simple"
- You can search for packages, see the list of results and install packages (nix search nixpkgs somepackage) (upon install add to flake file and "darwin-rebuild switch --flake ~/MacNix#simple")
