Edit posts, pages, or custom post types by adding a “/edit” to the end of the URL. If you are not logged in, you will be prompted to log in in order to edit the item.
Send clients pretty URLs to the admin instead of a ton of query variables!
The “/edit” functionality also works on author and taxonomy archives, and if you have a page assigned as your front page of your site.

This is useful if:
<ul>
<li>You are not logged in, and want an easy shortcut to edit an item.</li>
<li>You hate the admin bar and have disabled it, but still want an easy shortcut to edit an item.</li>
<li>You have clients. Send them a pretty URL with “/edit” on the end.</li>
</ul>

Add the option for a third column on the Edit Post and Edit Page screens. This is useful if you have a lot of boxes on your edit screen, from custom taxonomies and plugins.
Also adds a pair of mini columns underneath the edit boxes, giving you space for more small boxes.
