I really love it.
Just one minor suggestion, when the list of episodes requires a scroll (eg. Castle), the back and remove from favorites button should still be present at he bottom without a need to scroll.
Edit: I mean like S07E07. Great idea for a plugin though - I love it.
Currently there's no logic there yet. It's just a search that happens when you click the link. It automatically assumes that series aired today are available on tpb already, so it shows the magnet links there. That'll all change when i add the automatic monitoring and launching :)
