I have been using Emacs for 15 years. In that time, I have had large configs, spacemacs, doom, evil/non-evil. This is my current configuration. Package installation is managed via a home-manager nix flake.

I am surprised that I was able to remove everything surrounding vertico and go with fido-mode easily.

I have a parallel configuration that removes lsp and uses eglot, but it's not as fleshed out. I need to be able to use both eslint and typescript language servers and I don't have a reliable way to do that in eglot.

I am currently using emacs-head. I know I don't need to use-package builtin emacs packages but I do anyway.
