@b0rk As to config files: apparently I jump jobs quite a lot. Thanks to Nix and home-manager, at every new workplace, once I receive a new Linux or Mac machine, I can very quickly (now also thanks to https://github.com/DeterminateSystems/nix-installer) and easily get vim installed with exactly the same plugins and key shortcuts and config flags as on my home Linux machine. Also git flags (like 3-way-diff), aliases, personal scripts, and ripgrep plus a few other tools that I don't even remember but my fingers remember.
