Mark episodes as "listened" and make it possible to show/hide them same way as "read"
Right now the most common way of handling episodes is to enable automatic cleanup with possible delayed delete via Trash.
I propose to make another option - mark episodes as "listened" in addition to ability to mark them as "read". This should be done automatically after entire episode was listened to or manually (this is optional, but still may be useful).
If this is implemented, I would be able to filter and see only listened episodes, which are still marked as unread.
This way I can control deleting of listened episodes manually, instead of automatic cleanup.
This is how podcast app operated on old Nokia phones and I find it a bit more flexible.
Perhaps, it is possible to simulate this to some level by marking episodes as favorites, but it will be an ugly workaround...
