How do i ad <span></span> to the menu code?

[polyfragmented]

Assuming you're using the out-of-the-box navigation, in file /admin/inc/theme-functions on line 649 you find

Code:

$menu .= '<li class="'. $classes .'"><a href="'. find_url($page['url'],$page['parent']) . '" title="'. strip_quotes($page['title']) .'">'.$page['menu'].'</a></li>'."\n";

You can insert additional markup there. Please note that a later update to GS might overwrite your changes.
