I can't use the playlist anymore because the only way to add items to it in bulk is to enqueue downloaded episodes but that queues hundreds of episodes that I've played and deleted just because they were at one point downloaded.
Allow me to enqueue episodes I've played (ideally whether they're downloaded or not).
You can add to the playlist any episode you want to. You can use the select mode to select multiple episodes and then select the Add to playlist action. Feel free to contact me if you have any question (Settings/Feedback)
