This plugin allows you to easily bookmark/favorite posts, pages and custom post types. When you ‘star’ a post a shortcut link will appear in the admin menu. 
Use this plugin if you constantly find yourself editing the same posts or pages, and are sick of showing the list of posts first, then finding the post, then clicking edit.
Steps to use
<ol>
<li>Go to Pages</li>
<li>Click the Star icon on a page.</li>
<li>Your page is now bookmarked!</li>
<li>Repeat for other pages you always edit.</li>
<li>Save time!</li>
</ol>
Plugin Features

<li>Intuitive interface to bookmark posts using a star icon.</li>
<li>Zero settings! Activate and enjoy.</li>
<li>Works with posts, pages and any custom post types.</li>

<li>Setting a bookmark is done in realtime with no page reload.</li>
<li>Bookmarks are added to the admin menu for quick access under a “Bookmarks” menu item.</li>
<li>Adds a Bookmarks view/filter to the listing pages.</li>
<li>Bookmark shortcuts are also grouped by post type within the WordPress admin bar.</li>
<li>Optional “Bookmark Title” quick edit field to customize menu labels</li>
</ul>

Ever want your own shortcuts without mucking about with permalink structures? The Link Shortcut plugin allows you to create short (random numbers and letters, or short words) URLs under your blog’s domain that redirect (301 or 302, your choice) a user to other pages, either in your site or on another site.
In other words, instead of sending this url to the author’s plugin page: 
http://www.husani.com/ventures/wordpress-plugins/linkshortcut/
This shortcut could be created simply by installing this plugin and adding a link, via the same traditional WordPress UI we all know and love: 
http://www.husani.com/link123
You can also specify a specific “subdirectory” to be present in all Link Shortcut URLs: yourblog/go/STRING, for example.
YOU MUST USE NON-UGLY PERMALINKS FOR THIS PLUGIN TO WORK. Your permalink structure cannot be yourblog.com?p=84, it must be date-based, name-based, etc.
IMPORTANT: Link Shortcut creates a table inside your database. Upon deactivation, the plugin creates a backup table and copies records to it before removing the main table. If you decide to activate the plugin again — or have installed an upgrade — it automatically copies your backed up links to the newly created table. You can also delete the backup table if you remove Link Shortcut permanently.
