Many items in custom menus

Hello forum,

in case of many items in the menu the work of adding pages or categories to existing custom menus is a tedious work. The new items are added at the bottom of the custom menu, and need to be dragged some miles above to the right place.

Are you aware of a plugin, which allows to collapse the custom menus in the backend, thus making it much easier to drag the new items into the right place?

Thank you in advance!
