I don't know who designed the new 4.x smilies but they are horrible. They are so pale and bland that you can't tell one from the other for most of them. They are simply dreadful. They look like they were designed by a high school student. IS this supposed to be albino power or something?
Either go back to the 3.x smilies or go back to the drawing board. At the moment, I'm reuploading the 3.x collection with every upgrade.
