Recent History Dropdown

We're always looking for ways to improve our interface and help our users; this is a recent idea we're toying around with implementing. Often times a user might want to check a previous page where they've entered data, or customized filters in a report, so instead of needing to navigate back to that page, we thought it'd be nice to incorporate a simple "Recent History" dropdown that shows the last 5 pages, and we've saved the state/data of each of these pages too.
