If you’re a WordPress admin you probably want a plugin with the following features:
<ul>
<li>install, update and delete plugins and themes</li>
<li>it should be able to handle various locations, i.e. at least these <a href="https://codex.wordpress.org/Plugins#Plugin_Repositories" title="WordPress Codex Plugin Repositories" rel="nofollow ugc">plugin repositories</a> and maybe some from <a href="http://www.google.com/search?q=wordpress%20plugins" title="Google search on WordPress plugins" rel="nofollow ugc">somewhere</a> else.</li>
<li>basic search functionality for all these plugins and themes</li>
</ul>
This plugins lets you do (almost) all of these things.
Have a look at this <a href="http://www.youtube.com/watch?v=-BzX7bv3DgM" title="Introduction to Extension Manager for WordPress" rel="nofollow ugc">video</a> to see how it works.
<h3>Compatibility</h3>
This plugin was tested with PHP 5.2.x. Currently it won’t work with 
older versions, i.e. PHP 4. Please be patient until I’ve fixed that.
But it’s possible that this plugin will never work with PHP 4 because 
it’s likely that I will not find the time to implement that. So please 
consider updating your installation of PHP.
