When using emoji's there are a few that I tend to use much more frequently than others. It would be awesome if there was a favourites category in the emoji selector interface that allowed you to save and rearrange the order of your favourite emojis. ☕🤠👍🏻

I know that there's a "recent" category but that keeps changing as you use emojis and it shifts the emojis around all the time. In the favourites category I mentioned you could save emojis in a certain order and rearrange them as you like (and they would stay put in that order) so that muscle memory will allow you to select them that much quicker rather than visually hunting around for them each time.
