Thanks for your answer. I added fontawesome 4, too. Now it works.

At the moment I deleted the Yanone+Kaffeesatz in the plugin directly and replaced it with serif – but … this is not update safe.

I think you’re right. The idea with overrides for example to colorize links for specific sections in other ways, will be better and more neatly arranged.
At the moment I’m generating a dynamic css-file – works fine and I think I can redeclare it to usw it with such an options page.

Thank you for your help. I hoped there would be an other solution, but I didn’t found any, so I thought about discarding the whole projekt. But your idea is great. Thanks.
