Always liked how the says work in conjunction with emotes/poses, thought it would be really cool if we could whisper in emotes as well and have the whisper trigger the command.
So:
.lean over and .whisper in Bob's ear, "Got some shady biz, chummer, you ready?"
Other people see: "Steve leans over and whispers in Bob's ear, "G.. ..me ..d.. ..mm.r, .ou r...?"
Not sure if this would be difficult to code, but sure would be neat to have!
