So I just modified the new Panamericana.SkypeChatStyle from Skype 6.0 and added my modifications from Skype 5.1. did you notice the new chat icons? Anyway, the new Skype 6 theme isn't better than the styles before. But the old Skype 6 chat styles are not working anymore due to some changes. It's almost the same as Skype 5.1 Chat style. It's very easy, because it's just css - just like a little bit of Webdesign, what is part of my daily job as a Drupal specialist. The most thing I don't like of skype chat style is the waste of space.
