That’s interesting. I checked my sites again, both locally and on Ghost Pro. They both have this button when there is activity of more than 5 items. I’m attaching screenshot:
If you do not have access to the server, that means access to core files or database (even read-only) is out of the question and the only access to Ghost is thru the APIs which may or may not be enough. I’ll see what can be done about the 2 items you mentioned for post management.
