Doesn't remove the old "Parent Page"

Hi Robin,

You’re right, this plugin does not automatically “remove” the original parent page status, as this logic is pretty complex and wrapped up in lots of different ways in lots of different themes/plugins. For custom post types, the plugin should work just fine, but for pages and posts – which have a bunch of functionality for identifying menu parents already included in WordPress core, you’ll be required to do some manual filtering on your own, or simpler yet, some custom CSS and/or jQuery to simply hide the “parent” status of unwanted items in the menu. Best of luck!
