Allow Favorite Emotes

I've seen this suggestion before, being able to favorite emotes. Basically, it's a quick-access menu that you can add emotes without searching them

I'd like to mention that I'm aware this will be removed as a duplicate. But I do want to ask, if this has been suggested so many times, why has there not been progress on it? You'd think that if it's been suggested so much, that means people want it. So why is it not implemented yet?
