Add an auto translation option to chat messages.
As streamers we are held responsible for what is said in our chat. If we are unable to read/understand languages other than our own, that presents a big problem. Limiting users to only our own native languages alienates many of our audience from being able to chat. I would love to see an option to allow streamers to turn on an auto translate for chat to our own native languages.
I feel this feature would solve many problems with interaction with viewers from other countries. Twitch is after all a world-wide platform.
