@Moellenkamp: For this we don’t have translation option. We will work on this. I see that you are using Primary Menu and Footer menu. So, to change primary and footer menu label, just change the header in the following script and add it in “Appearance => Theme Options => Webmaster Tools => Header and Footer Codes => Code to display on Footer” box.
<script type="text/javascript">
jQuery(window).load(function() {
// Primary Menu
jQuery('#access .menu').tinyNav({
active: 'current-menu-item',
header: 'Menu'
});
// Footer Menu
jQuery('#access-footer .menu').tinyNav({
active: 'current-menu-item',
header: 'Footer Menu'
});
//Remove Old Primary Menu
jQuery( "#tinynav1" ).remove();
//Remove Old Footer Menu
jQuery( "#tinynav2" ).remove();
});
</script>
