Jack Reichert

This plugin was developed to display excerpts from random posts in a category. jQuery is used for fading the plugin in and out. It’s a great way for displaying testimonials of clients or just giving a snapshot of content from your site.
Shortcode added as of version 1.4
The most basic use is: <code>[reFader]</code> this will use the default options. 
Here is an example of all the options in use 
 [reFader title=”Random Excerpts” cat=”23″ type=”post” amount=”5″ length=”50″ duration=”5000″ linked=”no” url=”http://www.jackreichert.com/”]
This will show 5 (amount) posts (type) from category #23 (cat). It will show 50 (length) words from each post and fade out/in every 5 seconds (duration). It will not link each title to the corresponding post, but it will link all the titles to this plugins page (url).

Random Excerpts Fader

Creates a widget that takes randomly a number of excerpts from a category of your choice and fades them in and out.

Created to help those people who don’t like to edit code in template files (or are too lazy to do that). 
Just activate the plugin and it will automatically show the_excerpts in your homepage, archives and search results. 
It tries to display your custom excerpt text and if it doesn’t find it it will show an automatically generated excerpt. 
You can also define excerpt length, custom read more link and attach a thumbnail.

Auto Excerpt everywhere

Thanks to author for creating this plugin. 
It's works out of box. And working fine at WordPress Version 4.6.1


Works out of the box on WP Version 4.6.1

The plugin automatically displays excerpts instead of full post contents in your blog. Custom excerpts and generated excerpts supported.
