Allow chat to be turned off/diabled on the Mobile App.
I love watching streams, but I absolutely hate the chat. I want to be able to enjoy it like I would something on my TV and not be bombarded by hundreds of messages a minute of crap I have zero interest in.
You can already do this by doubletapping the screen or simply hit the speech bubble after you tap the screen once. Unless you have a very old version. Actually I doubt a version where you can't disable chat even exists.
