Big update! I'm skipping straight to V2.0 now, because the new script ADDS a row now, instead of replacing the

icon! Yay!

I also added comments to each line, describing what each of them do. The code's kinda hard to read, especially without a good reader with syntax highlighting, but you (some of you, anyway...) know how Javascript is with multiple lines...
V2.0
V2.0 (PMs)
It's almost kind of a new script... it's really not just for the :WTF: icon anymore. This script can be expanded to add any number of emoticons! Of course, it's currently pre-configured with the :WTF: icon.
NOTE: This one is named differently. Make sure you remove the old script, as the new script will not overwrite it.
It should be easy enough for you guys to figure out how to modify the script for your needs (adding additional emoticons), but in case you need help, just post back here.
