I'll just copy & paste my suggestion that got tagged "dupe".
Suggestion: Anything to make it easy to add smilies if you have lots to add. So far there is no real system in place to easily upload many smilies. Perhaps something like IPBreezy where you batch upload them via xml or something.
Anything to make it easy as the smiley manager seriously needs some work doing to it to make it easier for people to mass upload them/add them.
