Admin Menu Groups allows you to create nested menus in the WordPress admin sidebar navigation and organize all menu 
items in groups as needed.
A few notes about the sections above:
<ul>
<li>Create groups to organize the admin menu</li>
<li>Put less frequently used or advanced options in their own group</li>
<li>Hide unused items in the admin menu</li>
<li>Group related menu items</li>
</ul>

Admin Menu Groups

This is an underrated plugin. It is exactly what I expected: Keep my admin menu tidy since I see it almost everyday.

Especially impressive drag and drop tool. So I can make it works without finding any documentation like common plugins.

Thank you!

Underrated plugin

Admin Menu Groups allows you to create nested menus in the WordPress admin sidebar navigation and organize all menu items in groups as needed.

The lazy and the productive will love it : all admin links available in a neat horizontal CSS driven drop down menu. No need to click on “Manage” then “Pages” to edit pages. And plenty more space on your screen.

There is also an API for plugin coders (give your plugin its own special icon!).
