After an episode has ended, Channels app shows the details for the show just watched:
This is helpful sometimes, but more often I’d rather see details of the next episode so I can straight away choose to play it.
Given the UI is very generously sized, it would seem to me there would be plenty of space to add info about the next episode, including a play button.
My initial thought would be to divide the screen 2/3 and 1/3 with the 1/3 on the right being summary details for the next episode.
