Handy wordpress menu editing plugin?

Question

WordPress

Friends, tell me a plugin for editing the menu in WordPress. Standard tools do not allow you to add an item to an existing item, but add it as the top menu item, and then you need to drag it, which is very inconvenient for large menus. Well, searching for a page in the left block does not give all the results. I looked at several plugins - they concentrate on design, responsive, but my task is to edit the menu structure without touching everything else.

Is there anything normal for this?
