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!
