I found this wp-admin-menu-classes on Github, it works really well! You can pretty much rename, remove and copy any item or section within wp-admin. Very powerful and very handy!

That class plus this little bit of code I was able to change the navigation to suit my needs.
// Change wp-admin menu
add_action('admin_menu','admin_menu_changes');
function admin_menu_changes() {
rename_admin_menu_section('Custom Fields', 'Product Features');
}
