The latest Chromecast w/remote has this kind of functionality, and it's a real gamechanger. Kind of funny how we're right back where we were, price wise, but at least now you do the bundling yourself and can dial in what you are paying for.

it has made the experience much much better.
Not sure what else they'd show there. My Plex does the same thing; a list of things I can watch.
