As a follow-up to this discussion, I’m curious to learn exactly which dotfiles (user-specific application config) folks actually customize, and more importantly, rely on, as part of their daily dev machine setup.

For example, if you bought a new computer tomorrow, what would you immediately notice feels inefficient? Subsequently, what would be the first config files you would create in order to enable your “flow“?

Is it primarily just setting aliases and env vars for your shell (via a .bashrc/.zshrc/etc. file)? Maybe your editor and Git settings (e.g. .vimrc, .gitconfig)? Something else?
