Classification labels for emotes, and allow single-letter graphics, political emotes, etc
Single letter shorthands such as "W" and "G", or "press 1" have important significance in chats, and it is troublesome that streamers are not allowed to express these in an emote.
I suggest that the system change so that all emotes following Community Guidelines be allowed, under condition they are accurately labelled with all tags that apply, and a labeling system similar to Stream content classification labels be applied to by streamer to their channel emotes when uploading.
For example, Single-Letter emotes can have a classification of "Sticker" created that identifies the emote as a sticker reaction (Used in cases where the entire chat message will consist of the emote only). Prevents the emote from being used in the same chat message as other text or emotes, And blocks different kinds of emotes from being used in channels when certain settings are active.
Both channels and users in the chat should then have options to block, filter, or restrict emotes based on emote classification labels. Channels where political or more mature emotes are appropriate would have settings available to enable the additional types of emotes.
