Hi,
I can help you out here. That is an interesting idea, but we do not have an “Asmin View” of the calendar the way you describe it. There is the Front End Calendar and then all the events are in the backend for the admin to view, but it is not in the form of a calendar it is just the Event List, like the Post or Page List.
The option to “Hide From Event Listing” only hides events from the list view and does not make them private, the single view of the event is still accessible.
Let me know if you have any follow up questions.
Thanks
