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>

Adds a [post_thumbnail] shortcode for use with wordpress post thumbnails. Size can also be set using [post_thumbnail size=”XXXX”]. (You can call the function directly in your theme with <code><?php post_thumbnail('size=thumbnail');?></code>.)
Just insert the shortcode into any post’s content and when it will be replaced with the featured image.
This works only with the featured images introduced in WordPress 2.9.
