I would also like it, that if it doesn't find something that the popup disappears or being able to exit the popup with Enter when empty. Cant write my favorite emoticon :^) with ease :(

And a specific sorting could be added so that :) and :( which are already emoticons are on top so you can type it with ease

How does this work for simple twitch emotes like :) or a url where there is no space?
