We've added some emojis to chat which can be used similarly to discord. Example: :smile:
There's 18 of them for the time being, we'll eventually add more, so feel free to give suggestions and send feedback! We're still adjusting the size so let us know if they seem too large or too small.
If you're unsure how to install or update the pack, it's very easy! Select Mush Co. on your Multiplayer screen, click the "Edit" button, then enable "Server Resource Packs". That's it!
