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.

Try it with UberMenu – WordPress Mega Menu Plugin!

Is your Appearance > Menus Admin Panel running slowly in WordPress 3.6 or 3.7? Try the Faster Appearance > Menus plugin (there is an inefficiency in WordPress core)

Requirements

WordPress 3.5+
jQuery 1.8.2+ (comes with WordPress 3.5+)
Use of the WordPress 3 Navigation Menu System
Use of a modern browser, like Firefox or Chrome. (It does seem to work with IE, but considering this is a back-end script, that won’t officially be supported. Just use Chrome ).
