An embarrassment of emoji!
First, click the smiley in iMessage...Then drag the top off -- you'll get another window. You can even search from there as well... but that's not where it ends!Click the icon on the upper right...Now you have an even bigger window! And even more...You have things that are no just emoji, you have lots of other things to play with as well!Granted, not everything will come through in SMS since the character set on a phone isn't the same... but of the ones I've tried many of them seem to work fine.Just a little thing I found today! :-D
