I use Vim because I enjoy fitting Vim to how I think. But since the love story of Vim-based setups are long gone for you, I'd recommend picking up one of these new distros for Neovim — there are not as many i know about in pure Vim.

I've heard good things about Lazy.nvim and Astro.nvim.

I was fascinated by this when I first saw it years ago. But in today's world, where fuzzy-finding, and A.I. working off embedded vector databases is a thing, how relevant is this system — if the content being organized is electronic stuff on a computer. I get that this may work as a physical organization system.
