The WordPress 3 Menu Management System is excellent, but it can be a bit cumbersome if you’re managing many menu items. The Menu Management Enhancer for WordPress aims to improve the menu management user experience.

• Manage large numbers of menu items with ease
• Expand and collapse menu item trees
• Quickly jump to any top level menu item
• Enhanced drag & drop jump-to-item functionality
• View menu item IDs
• Child and descendant menu item counts at a glance
• The Menu Management Enhancer is a back-end (it won’t affect anything your site visitors see) administrative utility for WordPress which improves your menu management experience. It affects only the Appearance > Menus screen. If you have more menu items than fit on your screen, this plugin can enhance your menu management experience.
