It is still relevant, because if I click on the profile for the user, I still go to the edit page which shows the Community Builder Pro Header with those associated buttons, for change photo and change profile header image. — Personally I do not see a read for the buttons, because touching the profile header or avatar should be sufficient to start the edit process, but the change the header image still does not work.
OK, that reduces the search field size, but only insofar as it regards the right margin space. It still impacts the site logo on the left side.
I deactivated Youzify, and when, on the profile page, I touch the page header background image, I see the change cover button, now on the far right of the header, and when I touch it nothing happens. But what I do see know is that below on the profile page there is a tab always visible to change the header image. Still, the header is greyed so much it does not even look like the image I uploaded. And I would still like to remove the entire page header with avatar, when I am not on the profile page, since I can see the avatar well enough in the top bar.
