It would be interesting to be able to check out edits that was done some time ago, but in a rolling fashion. That is filter on yesterday, a week ago, or a month ago. The idea is especially interesting while patrolling new articles made by new editors, to give them time to finish the article before it is tagged with maintenance templates.
We wanted to do this but ran out of time. There are designs for how to implement—though we might have to go back to putting the # of days to search and # of results to show controls on separate panels.
