This is directly linked to my question(s) in this thread.
It's a real shame that at the mo only elves get to use the Rest Styles option. I suggest it's opened up to everyone and that more styles are added based on existing emotes/animations and maybe some new ones.
Most people I (and others anecdotally) encounter don't RP taking a very, very short nap when resting and sitting down for several seconds looks a little odd either way. It would be cool to be able to pray (and as I understand it, this is the animation already used for elves' reverie), for one thing! Anything that can look like a character is preparing for what's to come or winding down after a hard battle would be really awesome.
Some ideas based on existing emotes/animations:
praying (-kneel / altar prayer / elf reverie)
reading (no idea if there's a book reading animation, but the -read emote/scroll animation wouldn't be so bad if not)
stretching (some of the idle animations might work for this, or maybe the -dance emote)
adjusting gear (the -crouch emote / pickup animation)
lying down (if someone actually wants to faceplant, -lie or -fall could be used)
Then there are other animations that I think might be available but I haven't seen them, so I don't know how doable this is. According to NWN Vault wiki there's stuff like:
cross-legged sitting
meditating (if this is a traditional cross-legged meditation pose, rather than praying, it would be ace, both as a rest style and an emote)
kneeling (seems to be the kneel that happens before emotes like prayer, but even if it's taking a knee it might be a nice option for a brief "rest")
