The built-in menu editor for WordPress is a nicely built utility. But often with larger content sites you end up spending a lot of effort keeping the menus and the pages in sync. This plugin serves three major purposes:

1. Allows for easy creation of sitemap menus by removing the pagination setting for "View All" pages.
2. Allows for copying entire menus to a new menu.
3. Allows you to synchronize the parent-child hierarchy of pages with the parent-child hierarchy of a given menu.

The first feature is pretty clear, it's a pain to add say 150 pages to a sitemap menu when they are paginated by default at 50 pages.

The second feature allows you to copy an existing menu and play around with tweaks to the structure without losing the effort put into the original menu.

And the third feature is my favorite. Basically instead of going to every single page and modifying the parent/child relationship, you can create a sitemap menu and use the wonderful drag n drop feature of the menu editor to restructure your entire site.
