Regarding twitch turbo,

You currently get 2 free emoticon rows from twitch automatically, but one of my least favorite things about suggesting turbo to my viewers is the fact they get no emotes/badges of streamers.
I think its a good idea to allow someone to "subscribe" to 2 users emotes/badge because turbo is the cost of 2 subs regardless.
Possibly have it so that if a streamer does not have ads running (only pre-rolls) you cannot subscribe to their emotes/badge because you will not financially support them without the ad breaks.
