This Plugin will save your time by adding a duplicate button on each menu item while editing a menu. A real time saver. Currently it doesn\’t support customize screen, but I\’ll add it soon. If you find any bugs, just head over to support forum, I\’ll fix that asap.
Please rate me a 5 star if you find this plugin helpful 🙂

Nav Menu Item Duplicator

A simple plugin that adds a duplicate button to each items on edit menu screen.

This plugin uses an abstraction of jQueryUI’s autocomplete widget that interacts with the unofficial/undocumented Google Suggest API. 
Props go to Haochi Chen.
It adds an AJAX call to the search form, returning matches for the current search query. 
Make sure the searchform input field has <code>id="s"</code> applied, so this plugin can hook in the existing WordPress API to unfold its magic.

I will be more than happy to update the plugin with new locales, as soon as I receive them! 
Currently available in:
<ul>
<li>English</li>
<li>Serbian</li>
</ul>
