is simultaneous collaborative editing a real need though? I’d say org notes are usually edited by a single person, often from multiple devices, unless you are trying to create a Google Docs competitor, I don’t think that’s a feature that is actually needed.

git also has the advantage of complete history and easy rollbacks.

I’ve given up using Orgzly because the syncing is atrocious, it has restored deleted notes multiple times. I’m now using Organice with gitlab backend and it works very well.

IMHO the best way would be using git, which is literally made to resolve this kind of conflicts and it’s very battle tested. I’ve always had issues syncing notes until I switched to git.

It would be great to make it work without a backend, syncing files through the gitlab api, like Organice does
