/*   How to Rearrange/Hide WordPress Admin Menu Links
     Source: https://www.digital.ink/blog/wordpress-rearrange-admin-menu/
     
     1) Find the URL slug of relevant menu items (everything past the /wp-admin/)
     2) Re-order as in the first function. 
     3) Add separators as necessary.
     
     NOTE: If you don’t add an item to your custom menu order, and don’t remove it completely,
     it will fall in line below your custom order. So if you only want to re-order the first few 
     menu items (as seen below), everything else will display in its normal order below the 
     customizations you’ve made.

     To remove links from the menu:
     1) Insert the page’s slug (URL) in the "remove_menu_page" function. 
     
     NOTE: To remove multiple pages, call the function multiple times, once
     for each page you want to remove.

//This filter+function creates a custom menu order to replace the normal menu order:
add_filter( 'custom_menu_order', 'mysite_custom_menu_order', 10, 1 );
add_filter( 'menu_order', 'mysite_custom_menu_order', 10, 1 );
function mysite_custom_menu_order( $menu_ord ) {

     if ( !$menu_ord ) return true;
     return array(
          'index.php', // Dashboard
          'separator1', // First separator
          'edit.php?post_type=page', // Pages
          'edit.php', // Posts
     );
}

//This action+function removes pages from the menu; in this example, the Comments link is removed
add_action( 'admin_menu', 'mysite_remove_menus' );
function mysite_remove_menus(){

     remove_menu_page( 'edit-comments.php' );
