This plug-in limits the classes WordPress added to navigation menus to only those desired by the Theme owner, 
adds a unique ID to each <code>li</code> and removes any empty <code>class</code> attributes.

Navigation Menu IDs & Classes

At least some aspect of this plugin seems like it should be available in WordPress core. 
I understand the rationale for menu items having menu-item-ID, but it's pretty practical for them to have the slug in there, as this plugin provides.
Suggestion for plugin feature - offer option for slug prefix.
Like if I have a menu item "updates" I may use the class "updates" elsewhere, but class "menu-item-updates" would target the menu-item for sure. Of course I can currently use double selectors.



1 for inclusion in core

To reduce the extraneous WordPress classes and add unique IDs to navigation menus.
