Suppose you tell it to show you 4 episodes at once and you're in the middle of one. There should be a setting that allows it to keep replacing the other 3 with new ones but not the one that's in progress.
As it stands, you have to just give it a huge number of episodes to display and then scroll down to the one you were in the middle of listening to when you want to resume. I really only care about the newest episode and the one I'm already in the middle of.
I agree that we need a way to not delete episodes that are in progress. I'm going to be introducing the notion of a pinning an episode so that it is not deleted (http://mantis.snoggdoggler.com/view.php?id=1286). Pinning way work for this or simply just not deleting episodes that are in progress.
Thanks for the feedback.
