Hi bkrztk,
yes,
i've modified the templateDetails.xml and add the new modul position in the gk.const.php.
I've modified also the default.php, as you describe it in Step3 of your tutorial, but the module postion will be only display above or below the header.
What is the wright way to insert the new modul position next to logo, as in the above sketch.
Thanks you lots for your help.
Best regards.
Chris
