This new version for the Options page add-on adds a new parameter and function to control the menu names.

Previously, the menu text was dictated by the parent or sub options page title. Now, however, you can set 2 different values for both menu and title.

There is also a new function to customize the parent menu name!

New: acf_set_options_page_menu()

/*

*
*  @type    function
*  @date    13/07/13
*
*  @param   {string}    $title
*  @return  N/A
*/

acf_set_options_page_menu( __('Options') );
