Delete old episodes after X days (with the exception of favorites)

App version: 2.1.3 (Google Play)

Problem you may be having, or feature you want:
I follow several podcasts. So I download more podcasts than I actually have time to listen to. The result is that I have episodes around that are many months old and which I will most likely never play. It would be nice if the app would delete old episodes, which I have not added to the favorites, after X days for me. X should be user configurable.

Suggested solution:
Please add a user configurable option “delete old episodes after X days” – preferable in the in preferences/memory section of the preferences. This should affect all episodes older than X days, regardless of whether users have listened to them or not, unless the episodes were added to the favorites.

This would be really great.
