I saw in the forums suggestions thread that emoticons have been suggested. i'm not sure what the admins have planned, but I've made emoticon sets in the past for forums and I was going to offer to make some, but then I had a better idea.
hey! this is a gamedev site and there are plenty of artists. lets work together to create an emoticon set for the itch community! :)
here are some that I put together today. it's just my first idea. it would be cool to see other ideas. colors of course can be changed easily
edit: some more
