Swipe right to add episode to playlist from list of episodes, swipe left to mark as played
I spend the most time in my subscriptions adding new episodes to the playlist. In a list of episodes from a sub, I long press and select "Add to Playlist" or "Mark Played" if I don't want to listen to it.
If I could swipe left or right to achieve the same action. Perhaps make this available from the search section to add one-off episodes I might want.
