This looks PERFECT. I'll trial it out tomorrow. I can see on individual pages (books?) you're tracking changes, e.g. created and last edited. Are these changes tracked in a history page for version control by any chance, ssdanbrown/OP?
Most system changes (Create, Updated, Delete actions) are recorded and displayed in an audit log view for admins. As of the most recentl release, you can trigger webhooks upon any of these; Video example [1].
Changes to pages (where documentation content exists) do have their state changes recorded so you can revert/view/compare across versions of a page. The revision limit is set to 50 by default (I think) but this is configurable.
You can login to the demo as an admin to preview these features if needed [2].
