I like to keep my config minimal with most of my workflow in the terminal itself.
For example instead of using projectile or find file inside emacs I can just use fzf from the cli to fuzzy search my entire system and then open the selection in emacs.
Also I can use a kitty overlay to call fzf from inside emacs, which gives me the same functionality as nvim’s telescope.
Home manager puts your entire system under one config and makes it so easy to try different things that I’d rather not be locked into one ecosystem. 🤷
