Topic on Extension talk:Lockdown

Hi @Duesentrieb thank you for the great extension.

I wanted to ask you if Lockdown or another method would allow me to do the following.

1. Someone creates a page. That page is automatically ONLY visible to the owner (hidden from anyone else) but the owner can also invite others to see the page.
2. Only the owner (original creator) can edit the page, but they can allow others to edit it if they want.
3. The owner can choose to publish the page (make it publicly visible)
4. If they make they publish the page, the revision history of when it was private does not show, instead the revision history is reset and starts anew for the public version.

Please let me know, thank you.
