Increased User Management and Monitoring
In addition to receiving locked out notifications, I think overall user account management would benefit from more monitoring. It would be nice to see "active users" (people currently logged in) and the amount of time Section Editors spend working on their sites. This could get labor-intensive, but having an area where we can see page edits and additions would be nice too so we can gauge how often sections are being updated.

I would love to see some additions to user tracking. Knowing how often pages are updated seems more important than the last time a page was updated, but I will take both.
