I listen to podcasts basically in 2 modes. From the oldest episode to the latest or the other way around. Depends whether the podcast is the kind that reflects actual topics or is rather chronological.
What I really miss is
either a button by the list of episodes to flip the sort order or a per-podcast sort order configuration, so that I don't have to scroll to the bottom of the list for the oldest episode I haven't heard.
Actually even just one more option in the filter drop down menu would be fine.
You can go into Settings/Display/Podcast and enable custom sorting. After that every podcast will have its own sorting mode
