We'll create fresh WordPress site with Menu Humility installed. You have 20 minutes to test the plugin after that site we'll be deleted.
Some plugins (I’m looking at you, Automattic) put top level nav menus in the first menu group, right under “Dashboard.” This is annoying. These things are invariably less important than your posts, pages, comments, etc. This simple plugin (with no UI) shoves these line-cutting menus to the bottom, where they belong.
