I would like to suggest a new follower alert by Nightbot in twitch chat. Right now there is no way for a streamer using PS or XB to see a new follower in real time, and say thank you to the new follower which is a big deal to many viewers. A simple customizable message in chat from Nightbot triggered by a new follower would be very simple and effective at solving this issue.
Ex. Nightbot: YoYoGamingTv just hit dat follow button!!! Everyone show Him/Her some love!!!
