Congratulations on the launch. I can see that a lot of hard work has gone into building this. I could create an account and playaround a little bit. SSO login would be nice in the future.

Do you ever have to deal with atomically modifying two (or more) Y docs? e.g. when creating/removing relationship between two tables? if yes, did you have to make any changes to the sync protocol?

Hey … I am using a single top level Y.Doc for this … tables and relationships are separate data structures … relationships have auto-pruning enabled on them on diagram change
