Feature request: Group custom emojis in the picker when composing

[olivvybee]

The custom emoji picker on the web interface groups the emojis into sections determined by the instance admins.

When choosing a custom emoji in Ice Cubes, it’s hard to find the one I’m looking for because all the emojis are presented in a single list.

I would like to see them grouped in the same way as the web, so I can quickly select one by going to its category.

I'd like to say that I'd see this as a welcome change, since I was just about to create an issue with the same feature request. :)
