Removing Emotes From Autocomplete
I see someone has touched on this already, however, I feel it worth reiterating that it would be beneficial to delete emotes or blacklist them from appearing on autocomplete when users type : (colon) to start typing for their emotes.
Deleting emotes: it would be nice to be able to go through individual emotes and delete them on a case by case basis. For example, particular Hyperscape or Hype train emotes that just aren't appealing to a particular user.
Blacklisting emotes on autocomplete: a suitable solution for many people would be to simply make it so that certain emotes don't appear when trying to type out a word. For example, many streamers upload "hype" emotes to let viewers show excitement for something that is going on. I've seen many people complain that hype train emotes and hyperscape emotes completely bury other streamers hype emotes when trying to type out ":hype" to see the list of emotes that have that in the word. Blacklisting would be a good solution to both solve that issue, and keep emotes in their lists for the few situations they would be used.
