Set number of unplayed episoded
I'm a new Android user coming from iPhone. 1 feature I used a lot on my old player on IOS was to set a number of unplayed episodes.
I follow 1 podcast publishing 5 new episodes/day, and normally I only listen to the morning episode. This creates a lot of cleanup per day.
Edit: I just noticed settings>automatic cleanup. I'm guessing this has what you're looking for.
Don't know if any of these will help,
There is a batch download limit in settings>download, that can also be set per-podcast. It is probably affected by the "download older episodes first" option immediately following.
There is an episode number limit setting in settings>display>episodes, but the minimum is 50.
You can also filter episodes in the list by Recent (7 days).
If you're only listening to one episode a day, you may consider turning off automatic download in settings>download, and only downloading (or streaming) the one you want.
But I agree that some more fine-tuned filtering options would be helpful, like a setting for changing the threshold of "Recent."
