Qcode and Realm like to advertise their podcasts by dropping the first episode in the feeds of their other poscasts. Cool, I like being introduced to other stuff to listen to. I'm subscribed to dozens of the podcasts, though, and they ALL get that episode in their feeds, so I get a bunch of notifications and duplicate episodes added to my playlists.

Maybe this is common knowledge, or other people don't have this problem, but I just saw this in the settings recently and found it helpful, and thought other people might too. Go into the settings of each feed, then episode/chapter filter, and all your options will be there. You can also exclude trailers and bonus episodes if you wish.
