I'd love to see this! Sometimes when my friend makes me "angry", I make an unamused/angry face but it goes away in a second. Would be nice if I could keep it around for a bit longer. ^^; Would also be nice for other things, too. Maybe you have a very bubbly character! A smile all the time would be more appropriate.

Just a small thing but it would be a nice change. Although I'm sure there would be a lot of characters running around with ridiculous expressions all the time, haha...
