As I was testing some new themes I needed to change my main menu to 2 smaller menus. Since I wanted to refer back to my original them I did not want to edit my existing menu.

Creating 2 new menus from scratch (+/- 20 menu items) would cost quite some time. Evenually I found this small plugin and it is perfect for the job. Just install, activate and you can copy you existing menu to a new one which you then can edit to your needs.

Great small plugin, saved me a lot of time.
