Oh thank you very much! I have 0 experience with skin editing so I couldn't do it right.
Do I just need to copy "player overview panel.xml" from default skin and paste it in folder of Mustermann?
I love the look of this skin but I don't use it because I can't get used to the type used to show the attributes. Would it be possible to have a Mustermann version showing the attributes as the default skin?
