This adds navigation buttons to the bottom of every page. Just upload SimpleMenu.php to your sites root, and _sub_footer.html to /templates/tmpl_uni and you're done.
Add a language key for '_footer_menu_text' or delete this line from _sub_footer.html if you don't want to use it:
<div style="width:48%;float:right;"><bx_text:_footer_menu_text /></div>
