If I go to the Audio tab and select 'All - sorted by feed/date', I get a sorted list of all the downloaded episodes by date. Is there a similar feature for the feeds tab? i.e. I want the feeds to be sorted according to which feed has the latest episode waiting to be downloaded.
Nope, not at the moment.
But using the New and in Progress filter n ay be helpful as it would show you orly podcasts that have unplayed eoisides? You probably knew that.
