You can download and make your own emotes, I don't know if the staff intends on adding any new ones. You can also edit the existing emotes.cfg file and edit the emotions. The codes to are at the very top of the file.
Dance moves, I would love to see Moonwalk and Thriller from IT added back eventually. But before dance moves, I want actions. Like, tail twitch, paw raise, ear flick, etc. You're kinda.. like, stone, if you say.. just sitting/standing/laying is nice, but have you noticed the characters really don't make any movements? I liked how in IT the eyes moved, I want moving eyes back actually. xD
But these are good, the only one I'm not sure of is the Combat. But I never really liked PvP, so that's just me.
