Sub Emote Search
There needs to be a possibility to search sub emotes by emote code. Previously twitchemotes.com offered that functionality but that got removed.
Being able to search for sub emotes by their code (for example when you need a new "Frustrated"-emote because this feature not existing frustrates you) helps viewers find emotes they like and can help especially smaller streamers who might stay undiscovered otherwise to get brand new subscribers.
The streamer that I have been subscribed to the longest is because I found them through searching for a certain emote. They had it. I love it! The streamer has a sub for life as long as they have that emote.
A little clarification because some who i've shown this idea to didnt understand it right away:
What is meant is a sub emote search through ALL sub emotes on Twitch and not just searching through emotes that you have because of your subbed channels. (That feature already exists so it would make no sense to suggest that.)
