Are you aware of Audiobookshelf[1][2]? While Cardo is a very cool initiative, I wonder if considered joining forces with Audiobookshelf as it might save up some duplicated efforts :)

audiobookshelf looks more like a media server for mostly audiobooks, a la plex or jellyfin -- + podcasts as an extra thing

whereas cardo seems to be a standalone desktop app just for podcasts

not really in the same category
