Hello, it would be nice if the header, including the navigation bar would float on top when we scroll down the page, so we don't have to go back to the top of the page if we want to use the navigation bar.
Mmmm... I just tested it to see how it would look, and doing it that way is pretty obnoxious to be honest.
In the Drupal module named administration menu, it is an option, disabled by default: Keep menu at top of page If enabled, the administration menu is always displayed at the top of the browser viewport (even after the page is scrolled). Note: In some browsers, this setting results in a malformed page, an invisible cursor, non-selectable elements in forms, or other issues. Disable this option if these issues occur.
Yeah, it's not hard to enable... I just think it looks bad. And even worse when the browser window is small (like a mobile phone).
