EDIT: Noticed a little bug on Windows, you can't add a podcast while it's playing, at least not by pasting the address, it immediately wipes out the field. Had to pause playback in order to add another.
As an Antenna Pod user this could be really great. I've been starting to use Audiobookshelf for Podcasts because I haven't had success with syncing in the past, but Antenna Pod is still a better UX so I'd like to be able to use that.
