It would be really nice to see "last viewed" in the cards view in order to bulk delete cards that are orphaned and haven't had views since a selected time. It would also be nice to be able to tag cards somehow. I know there's workarounds using workflows to rename them, but this would be a much easier alternative. It would also be nice to have the option to see what dataset powers the cards, or if the cards are orphaned in the sense that it is not powered by a dataset (if the dataset was deleted). This will help make cleanup so much easier. The ability to filter on datasets and dashboards is more robust than the card level filtering in the admin view.
