To keep content accurate and up to date it would be very helpful to have a way to list all pages which had no recent update for xyz dates. Similar to the Brows>Activity or Brows>Pages>Tree view it would be great to have a way to list pages "older" then a certain age. This would allow a admin to send reminders to the contributors of a a page to update the page or review the content and confirm that the content is still accurate.
