To add to deeper face options, there could be face poses.
Like rolling eyes, frown, raised eyebrow, salty wink, face palm, smile, grin, laugh, pout, sticking out your tongue, playing with your hair...
Maybe when you type the emoticons or actions like lol, /me laughs, : )), /me pouts, :facepalm: your character does the actual action?
I will probably look like I am having a seizure the amount of times I use and lol. I will have to follow it with the special dribble to finish it off : )~
face expressions would be really cool, even to just be able to smile, laugh or frown
