Thanks, that's interesting! We're using Joplin to share lab notes and use the sub-notebook structure to create a note per day (using journal plugin). The tags would allow every user to find all notes that e.g. are related to a specific part of the experiment, it would thus make sense for us to share them. At the same time we want to allow the users to have individual notebook, so we want to circumvent login via the same account. Do you see a way of making tag syncing/sharing optional?
