It was great to see new episode notifications introduced in 2.2.0!
Once I got the new version, I wanted to set all my existing feeds to notify me on new episodes, which I managed to do by running SQL against a backup of the database (update feeds set episode_notification=1;) then reimporting.
A nice feature would be the ability to do this in the GUI for all feeds with a single action, without editing every feed individually. (Sorry if I’ve missed an existing way of doing this!) And also to be able to set the default for new feeds.
