Does this do the trick?
public function nav_user_search() {
qa_html_theme_base::nav_user_search();
echo '<span style="float: right; margin-right: 5px">[N]</span>';
}
Of course, change the CSS to whatever you need. Actually, you'll have to change it to support all media queries.
Additionally, as this will change your HTML structure this might break the way it currently looks in other themes. I would advice against changing the HTML structure and in favor of only changing CSS when switching between themes.
Plan B would be to move the [N] using jquery... that way you'll be dynamically modifying the DOM while keeping the original HTML intact... kind of dirty, if you asked me.
As a side note, I also find it annoying having to make a click to see my points :@
