I would love a better selection of geoguessr-specific emotes. There isn't even a good emote for 'good guess' - you either have to use GG or the brain exploding one. It would also be good to have one to indicate that it's somewhere you know from real life, or that you were just super lucky with guess. I'm not sure what else or what they would be, but I'm sure there are lots of interesting options.

I don't pay for Pro Elite because I'm not very interested in the avatar costumes (I'm happy with my current costume!) but I would definitely pay for Pro Elite for better emotes.
