Don't hide the active element, it annoying to use the navigation if the
menu items changing there position with every click. Indicate the active
menu item instead, similar to the header navigation.
May I've worked to long with windows systems, but help and about have to
be the last menu items :-). I've reorderd the menu items to what I think
user need more often.
A sub-navigation should not change its parent heading. Changed that as
well.
