For the Weekly Overview of my Calendar-Extension I prefer the position before the navbar. Would be great if you could add a template-event
EVENT navbar_header_before
in the /prosilver/template/overall_header.html before
INCLUDE navbar_header.html
and the same
in the subsilver2\template\overall_header.html before
div id="menubar"
