In the latest beta, custom emotes are finally being implemented. This is amazing! I think it could be even better though.
Just like how Discord servers can upload emotes for anyone in the server to use, Groups should have emote slots that the group owner/admins can upload to that any user in the group can use! For example, the Shelter group being able to upload a Shelter logo as an emote, that now anyone in the group has added to their custom emote menu.
