Emotes are a big part of the Twitch experience, and many streamers have different emotes for different occasions (special themed streams, certain games, holidays, etc.).

Instead of having to manually swap out emotes individually, being able to create sets/groups and then being able to toggle between them would save a lot of time. Additionally, it would be great if this ability to toggle sets/groups could be added to the Emotes API.

Another option would be to offer Emotes API which allows Emotes to be individually swapped between active/inactive slots (which would allow streamers to create sets/groups without the feature being integrated into Twitch), as suggested here: https://twitch.uservoice.com/forums/310213-developers/suggestions/43568049-allow-use-of-api-to-swap-active-emotes-in-and-out
