Filter Podcasts library by unplayed episodes

For users like me who are subscribed to a lot of podcasts, it would be great to have the option to filter the Library and/or Shows by number of unplayed episodes, hiding the shows with no unplayed episodes available. Currently, I have to click into each show to see which shows have new episodes to access.

The sorting by Date Last Updated is fine, but it doesn't really indicate whether there is new content for me to listen to, as I listen to podcasts daily and don't remember the number of unplayed episodes still remaining per show.
