<p>If you want to graphically display a random list of your posts with their featured image in the side bar, then this is the plugin for you. This plugin allows you to set the category IDs (or all categories) you want to pull the random posts from, the number of random posts to display, the maximum width and height of the featured image thumbnail, the widget title, and the colors of the surrounding box.</p>

Puts a list of clickable random posts with their featured image in your sidebar as a widget, this list is customizable.

<p>Randomize simply displays randomized text. You’re able to deposit text passages, quotes and HTML code in the administration backend by categories. You can use the widget, a shortcode or template tag to show up randomized content on your site.</p>
<h4>Ready for translation</h4>
<p>Since version 1.4 was released Randomize is ready for translation. Feel free to add or support your language on <a href="https://translate.wordpress.org/projects/wp-plugins/randomize" rel="nofollow ugc">translate.wordpress.org</a>!</p>
<h4>Development Notice</h4>
<p>The original author has discontinued the development, so that I decided to continue the free distribution under the new name “Randomize”. It’s based on “Random Text” by pantsonhead.</p>


Randomize

The plugin does what it should and the bulk actions and categories are super solved! It would still be nice if you could output each widget with an indvidual class or format such as Div, H1, H2.

Works well

Store and display randomized/rotated content by categories in sidebar widgets, pages, posts or templates.
