Shall the parameter be Application, ETP or subsite-wide? If you say application specific, then I will upload a new subnavbar without <include> functionality. If you say ETP wide, I would ammend all the current ETP applications to make use of that parameter. And last but not least, if we make it subsite-wide, I would be looking into adding this to the weblogger (if it could be done easily). Someone else might then go off and add it either to the richtext widget or create a new widget type or manually edit this in each package.
