A Correspondent bemoaned the loss of the "Mark as..." contextual menu item when control-clicking a Podcast library subscription title while in List View. I wouldn't have noticed that in a million years. Still, it's an expulsion only slightly more arcane than doing away with my beloved Mute button, so I was sympathetic, and produced Mark All Episodes As Played. While the Podcast library is in List View, select any one (or more) episode(s) of a podcast or its subscription title and run this script to mark every episode of the podcast as Played (or Watched). Works great when assigned a shortcut.
