Not support it currently. However, a single markdown file can be treated as one block. Therefore, all the clues are ready in nb-crdt and nb-editor. One tricky part is the frequent replacement and conflicts of xxx.md files for file-based synchronization. There may be significant differences between file systems. Anyway, I think it could achieve eventual consistency by automatically generating folders like xxx.mds in the same path to manage it.

Yeah, but you lost me then. Either Markdown is the source of truth (and you do the CRDT when one is edited and reconstitute it after) or I won't store my notes in your app :)

I've heard that CRDT needs to be the source of truth for certain features to work (handling users going online/offline?). I was never quite sure why it would not work to just create a new CRDT document from another source of truth (markdown, database, ...) when starting an editing session. Maybe someone else can explain.
