Make chat customizable so streamers can turn on/off different stuff and combine them like badges/colors etc and make each chat unique.
In my case I'd like to turn off nickname color, combine all badges into one (i.e. if viewer is a sub and prime one then he will have badge with crown, if he is sub and moderator then he will have badge with green border), in case of regular viewer (just follower but always watches the stream) then he will have his nickname color
Of course, if there was a way that I could turn off chat emotes without resorting to using browser scripts and Chatty to both participate and read chat.
Just that the spamming of emotes tends to get on my nerves.
