This plugin allows you to display an unordered list of post (or custom post type) links (with title, featured image and exceprt) to a specific author (or multiple authors), category (or multiple categories) and tag (or multiple tags). It can be called either with a shortcode or from within a theme file.
To call it with a shortcode, use <code>[latest]</code> below are the attributes you can use with this shortcode: 
* Authors: 
 [latest author=”username or multiple usernames separated by comma”] 
* Category: 
 [latest category=”category name or names separated by comma”] 
* Tag: 
 [latest tag=”tag name or names separated by comma”] 
* Post Type: 
 [latest post_type=”post type name”] 
* Show Posts: 
 [latest show=”number of posts to show”] 
* Show Excerpt: 
 [latest excerpt=”true (default is false)”] 
* Show Thumbnail: 
 [latest thumbnail=”true (default is false)”]
To call it from within a theme template, you have to wrap it in this PHP function: <code><?php echo do_shortcode('your shortcode goes here'); ?></code>
