I dunno if this has ever been suggested, but if it has, I apologize ^^;
I was thinking, would it be possible to have a winking emote action(s)? Like, as your char winks, one (or both) ears goes down and sticks out his/her tongue a bit with a smile (I suppose you could call it a silly or blushing wink), and the other just a normal wink (both ears up and a smile). Just a couple ideas I just thought of ^^
