Use this plugin when you want to display a list of recent YouTube videos from a 
channel or playlist in your site’s sidebar.
This plugin is a fork of Aleksandar Urošević’s <a href="https://wordpress.org/plugins/youtube-channel/" rel="ugc">YouTube 
Channel</a>. This plugin is much 
more lightweight and does only have a subset of YouTube Channel’s features.
The videos are each only presented with a thumbnail, and optionally also its 
title and/or description. Clicking a thumbnail takes the user to the video’s 
page on YouTube. This results in a much smaller codebase and no additional 
front-end dependencies. The original plugin, YouTube Channel by Aleksandar 
Urošević, on the other hand depends on several JavaScript libraries 
(<a href="http://jquery.com/" rel="nofollow ugc">jQuery</a>, <a href="http://fitvidsjs.com/" rel="nofollow ugc">FitVids.JS</a> and 
<a href="http://dimsemenov.com/plugins/magnific-popup/" rel="nofollow ugc">Magnific Popup</a>), which 
potentially makes the whole WordPress site both slower to load and use.
