Let the content creator can change the background theme of the chatbox. So, it can be more than the normal White or Black theme chatbox. What do I mean about that, I'm talking about a little bit of customization. The content creator can the background color to Red, Blue, to Twitch's iconic Purple color, or whatever they like as long it's following Twitch's TOS. The letter's color will automatically change to adapt to the background color, so the viewers can still see the chat easily.
