I think my favorite feature is its good toolkit for speeding things up. I listen to most podcasts at about 1.4x, and there's a button for removing silences. I have no idea how they do it, but it doesn't sound unnatural. It just peps up the pace and makes people sound more lively. I've used other apps and their speedup algorithms aren't as good.
All told with its various speedup features, I download about 30 hours of podcasts a week, but I probably spend half of that actually listening. (At least some of that is ditching episodes I find dull, but not many.)
Other than that I really am just used to my "workflow". New stuff gets downloaded and added to a queue. I imagine most podcast apps have something like that, but this one has a nice feature set for managing it all.
