Include episodes left progress bar for Now Playing episodes

Just an idea, per mock-up example - nice to keep this info visible even while in the middle of watching an episode, and keeps all elements aligned if the watching progress bar is set to appear below the actions.

However, I appreciate this wouldn't work with the current option to move the watching progress bar inside the poster.
