I'd suggest another /wave emote that says more "hello" and not so much "hey, over here!" Similar to the /goodbye wave but one that doesn't say goodbye.

Also, something of a combination of /makeface and /taunt. Maybe called /sillyface

/checktail or /groomtail, random idea for the Mi'qote,

/lalapat could pat a Lalafell on the head

/facepalm just needs to happen already, haha.
