Featurer request: Command line flag to determine whether header is to be shown or not for new windows?

[Ralf_Reddings]

I am trying to spawn new windows that do not inherit their look, panel, etc etc from the most recently active window (I think this is a default feature). I can determine most things with the command line but I am missing a flag that I can use to show or hide the header (toolbar for details or thumbnails view) similar to "-no-preview".

Thank you
