Add pages, posts, or any other custom post types to any of your registered WordPress menus directly from the post editor page. Check the checkbox for the menu to add a the post / page / custom post type to, update the post / page / custom post type and it will then be added to the top level of all the checked menus.
You can control which post types display the ‘Add to Menu’ meta box by going to the ‘Settings > Post to Menu’ page.
If the post type has hierarchal structure (such as parent Pages), this will try to place the new menu item underneath a menu item that links to an ancestor post (if menu item exists).

The admin bar replicated functionality that the admin menu accomplishes, why have two menus? Now you can have one menu bar that does pretty much everything you could ever need. This plugin adds the admin menu (the menu on the left side of the screen) to the admin bar. The admin menu is ‘fixed’, like the admin bar so that it will appear no matter how far you have scrolled down, keeping it easily accessible and consistently in the same spot. The screen options and help menus however do not, so keep that in mind.

Ultimate Admin Bar

Move the admin menu from the left of the screen to be incorporated with the admin bar. Significantly reduces the admin menu screen real estate.
