make it possible to reply to messages without opening up a new message window - i.e. allow users to repond from within the inbox list.
I get a lot of short compliment messages from guys on this site. Just short compliments, nothing else. I'd like to be able to say a quick "thank you" or do a "nom" on each one, but opening up each and every message window just takes too long, so I don't even repond to most of them. They pile up too quickly. Nice problem to have, yes, but I'm just not going to spend up to a full minute on each simple "thank you" response. It would make this site a chore, not something fun.
