I don't know if there out is a hack to get maintoolbar + locationtoolbar in one line... but i did it by myself.
I get all normal bottons, location-depending bottons (in kghostview for exemple) and location toolbar (I tink find combo should work too). :)
-remove locationbar section
-maintoolbar section should be like the download (i can't put it here...)
I hope this work for anyone who prefers this toolbar way and in a easy way...
