"Duplicate Menu" duplicates menus

Although this plugin has not been updated in a long time, it worked fine for me. It does one thing (duplicates a menu). It either works or it doesn’t — it worked. My menu wasn’t particularly large, but duplicating it when I needed modified version still was a lot easier than starting from scratch.

Why WordPress is so stingy in offering options to copy things (menus, pages, posts, you name it) is beyond me. Thanks to the author for a much-needed piece of work!
