This is a suggestion, but a BTTV mobile app would be awesome! A way to be able to use BTTV emotes in messages, something kinda like Bitmoji. Now I’m guessing it may never happen, but it would be cool to see. Also part of that app is a Twitch watch feature so people could see BTTV emotes in chat on mobile, not in the Twitch app.
