An issue I just noticed with the Google TV OS:
I am not able to add recommended movies on YouTube which appear on the home screen to the watchlist in Library tab. Recommended movies from all other streaming services, I am able to add to this watchlist. If I long-press the centre button on remote on a YouTube video which is shown on the home screen, I only get an "Open" option. For all other videos, I get many options like Watchlist, Already watched, Like, Dislike, etc.
