Provide access to all versions of a current draft, over time or at each save point

Today I lost some work in Confluence due to a bug.

I would have been able to restore my work had there been an ability to access versions of a Draft (rather than a page). Currently drafts are only saved as the most recent saved draft version.

The bug I encountered restored the original page that I was working on, making the draft of the page revert back to the old page version.

As I was editing the page for over an hour, being able to access a version of the page saved every 2-5 minutes, and then select the appropriate version would have been very helpful. Keeping this information for the current draft and most recent saved page version would have allowed a way out of this problem, which was introduced by unexpected behaviour/bugs.
