Those all sound great. I'm a particular fan of the laying down (on ground) emote, since right now you can only do that on beds and beach chairs.

My feeling on persistent emotes is that if the devs are thinking about adding a new emote, persistent should be the default, and they should only make it non-persistent if the particular emote doesn't work for it. I can't stand that things like /converse and /elucidate aren't persistent.
