Private sandboxes
Proposed by Sparrowofsong

Proposal summary: A private sandbox page for users, may or may not be tied to wiki they're using.

Full proposal: Basically, a version of a user's sandbox that is only visible to that user. This would be useful for users that want to prepare a page for information that shouldn't be public yet -- for instance, leaked content for a TV show wiki, or content in a personal game's wiki that the rest of the players don't know. This way, pages with that sensitive content could be adequately formatted, tested, and saved without being visible to others, which lets it be published much sooner than if the user had to wait until the information was already known.
