I love the streaming feature in Poweramp that allows you to stream the music on other devices in the same network like Smart TV's.
It currently shows the cover image on the TV screen when you use the streaming feature. Since Poweramp has a lot of visualizations I think it would be a great feature to have an option to play/show/stream them on TV's, especially since the basic streaming feature already exists. The visualizations would probably look amazing on big TV screens. Of course it's nothing essential but it would be very nice to have.
