Hello,
It would be useful and stylishly beautiful, position the profile header on a full screen position so that you can place modules below the profile header (not side by side that graphically shrinks the header and is not pleasant). I mean:
example: (in protostar) header in "position 1" (all the screen from left to right) and the module (example adsense) in position column 8: (it remains under the header)

Now if I want to put a module in the column ,position 8, the header shrinks and the graphic view is not beautiful.
