Yes, on Amethyst you can watch zapstreams in app and join the chat. Also all comments in the chat appear in feed under a banner for the zapstream, creating a fantastic marketing for the zapstream. What is limiting is that you can't currently use the remainder of Amethyst while watching the zapstream. Picture in picture would allow for watching the zapstream while still noting, scroll and chatting. Seeing Nostur casually kill it is fun.
