Like what happened with cheering recently, I think it would be a really great idea if streamers were able to make custom badges for gifted subs (especially because the highest gift sub badge isn't high enough; see my comment to https://twitch.uservoice.com/forums/310231-subscriptions/suggestions/38573176-add-higher-sub-gifting-badges). Additionally, streamers should give custom emotes if users have given a certain amount of subs.
