Every note taking tool/app I have attempted to use is lacking in _some_ way.

I have tried:
- org-mode
- various electron apps (obsidian, logseq, anytype, standardnotes.. probably others)
- tiddlywiki
- plain text
- paper (bulletjournal, index cards.. etc)

All I want is something that:
- powerful search
- [[]] style backrefs
- works on openbsd
- works on ios
- syncs without needing 3 apps and needing to manually merge things every day

What does everyone else use for #notes / #notetaking?
