+  Höchstens zwei Ordner pro Abo vorschlagen, nur hinzufügen, nichts entfernen.
+- Stufe (nur wenn angegeben): "queue" = Stamm (neue Folgen auf die Merkliste und geladen) – für Podcasts, die
+  regelmäßig gehört werden; "inbox" = Strom (neue Folgen nur im Strom) – der Normalfall; "ignore" = Auf Abruf (nicht im
+  Strom) – für Abos, die kaum gehört werden und deren Folgen im Strom nur stören (z. B. sehr häufig erscheinend und
