Do you have a particular configuration or set of extensions you've been looking at? I mostly use JetBrains IDEs but have been trying to get a decent neovim setup as well. I followed some random tutorial and eventually got a decent setup working but it feels fragile and I'm not sure I could reproduce it if I had to. I am looking at AstroNvim now as a potentially more stable/reproducible setup.

With editors like vim, neovim, emacs, it's way easier to get the lay of the land first (tutorial, play around with the default config,..) and then list out what you need.

My vim config has three things only: LSP, FZF (for anything fuzzy), and Plug (to install the above two). There's also a few niceties, but I could do without them. or vendor them into the main config. But it's not my daily editor, so that's just the base config. Anything I could add on top of that would depend on the projects I would need it for. That's about 200 lines (the lsp config is 1/4 of that)

NB. A nice talk even if it's about vim "How to Do 90% of What Plugins Do (With Just Vim)"
