the beauty of layer tangling! I love that you have a look at that. I realllllly mean it.

But maybe I could also add a mechanism to let each class defines it's own icon. pay attention to speed :). But yes I do not know how this is implemented right now. Now DO NOT LET PEOPLE NOT COMMENT THEIR $^%&*() CLASS. GUYS IF WE WANT COOL ICONS => WRITE COMMENTS If we all sit down and write decent comments then we will have both: a nicer system and sexy icons. So for me the choice is clear. Focus on your exams :)
