Also Vim user, and I've always been a little baffled by org-mode in general. There are several Neovim plugins that try to replicate it (either real org-mode compatibility or just a spiritual association), and I've really struggled to understand what the use-case even is. It just seems like so much overhead to even grok org-mode, keep a sane and meaningful hierarchy of your ideas and keep it up-to-date... seems like a ton of work over just using your inbox and calendar as your "external mind". People constantly sing its praises and the advantages it brings but I've never seen it articulated what those actually are.
