Most of the plugins and even standart WordPress tabs in the admin menu are not used very often. 
With this plugin you can make rarely used items in the admin menu invisible until you need them. 
You can just toggle them whenever you need them with Toggle Extra button in the left menu.

Clean WP Admin Menu

Still works!

You can make rarely used items in the admin menu hidden.

This plugin uses a combination of WordPress hooks, CSS (when possible), and Javascript (last resort) to removed specified admin interface elements. These elements may be considered by some to be superfluous interface elements that are undesired for one reason or another, so this plugin aids in their visual removal.
Each admin interface element is individually selected for removal. The elements that can be removed are:
<ul>
<li>The header WordPress logo (bear in mind this functions as a menu) in the admin bar</li>
<li>The home icon next to your site’s name in the admin bar</li>
<li>The “Howdy,” greeting before your username in the admin bar</li>
<li>Your username link to your profile in the admin bar</li>
<li>Your avatar in the admin bar</li>
<li>The Dashboard menu link in the sidebar</li>
<li>The contextual “Help” link</li>
<li>The footer links</li>
<li>The WordPress version in the footer</li>
</ul>
(There is an associated screenshot which points out these different sections.)
Note: These settings are global and will affect all users who are able to visit the admin pages.
