A few years ago I switched from Linux to macOS, but my workflow didn't change a lot. I just need a browser and a terminal emulator. The majority of my work is done in a shell with a handful of tools.
Everyday, I use Nvim, git, tmux, and zsh (profile, shrc) and thus these config files are the most customized.
Have fun reading them and steal what you need.
