<p>This plugin allows you to easily dequeue styles and scripts from your site’s queue.</p>
<p>It also allows you to check which ones are called from the Archive, Single, Page and Frontpage templates of your site.</p>
<p>Once you used it, you can copy&paste generated code to your plugin or theme files.</p>
<p>This plugin can break your site frontend, so be careful when using it. If you don’t know what you are doing, please don’t use this plugin.</p>
