Super Widgets let you display the Title, Featured Image, and Excerpt of a selected post or posts in your sidebar.
Narrow down posts to feature by blog (if multisite), post type, or taxonomy.
Show a single post (post/page/custom post type) with the Single Post (Post Type) widget.
Show the most recent post in a selected taxonomy with the Single Post (Taxonomy) widget.
Show the most recent X posts in a selected taxonomy with the Multi Post widget.

Super Widgets

<h4>Provided Custom Hooks</h4>
This plugin provides 2 custom filters:
1) Change labels and other arguments passed to register_taxonomy function: 
 add_filter( ‘media_category_args’, ‘my_media_category_args’ );
2) Hooks inside the category postbox HTML used to edit individual file information: 
 add_filter( ‘media_category_html’, ‘my_media_category_html’ );
The use of these hooks are recommended, thus, if the plugin gets deactivated, those hooks will not be called anymore and then you get things consistent and clean.
