In 7.1, if you click on a tag or author name, you basically see the exact same page as the parent collection page but with the filtered results. Unlike 7.0, there is no visual indicator (i.e. text) to tell you what exactly changed and how your results were filtered.
Am I missing something or is there a way to display how exactly you filtered, such as with a "Filtered by tag XXX" in 7.1?
