<p>The plugin adds two taxonomies to the WordPress media library which are then available to categorize and tag your attachments. By default, these taxonomies, although sharing the same names and behavior, are separate from the default post taxonomies, but this can easily be changed if desired.</p>
<p>The plugin follows WordPress Core principles and offers a lightweight alternative to similar approaches which often tend to be incredibly flexible, but at the same time complicated and bloated. And if you have a little knowledge of code, you should be able to adjust the plugin exactly to your needs if the default configuration doesn’t satisfy you.</p>
<h4>Features</h4>
<ul>
<li>Adds categories and tags to the Media Library (independent from the regular post categories and tags)</li>

<li>Adds a setting for the default attachment category</li>

</ul>
<h4>Quality attributes</h4>
<ul>
<li>Lightweight plugin following WordPress Core principles</li>
<li>“Decisions, not Options”</li>
<li>Can easily be used as a must-use plugin</li>
<li>Provides a flexible API to add other attachment taxonomies or disable the existing ones for developers</li>

</ul>

<p>Post Category Filter allows you to filter your post categories and custom taxonomies by adding a fast and intuitive search box on top of the term lists. As you type, the list updates instantly and shows only the categories or terms that match your query, making navigation quick even on sites with hundreds or thousands of entries.</p>
<p>This plugin is designed for users who work with large WordPress websites, complex content structures, or extensive taxonomy sets. Instead of scrolling endlessly through long category lists, you can simply type a few letters and immediately locate the term you need. It provides a smoother editorial workflow and helps reduce time spent searching for the right category during post creation or editing.</p>
<p>Post Category Filter works seamlessly inside the WordPress admin interface and supports all public taxonomies, including custom taxonomies created by themes or plugins. It does not modify your categories or database in any way. It simply adds an efficient, lightweight search layer to help you manage and assign terms more effectively.</p>
<p>If you maintain a high volume of content, run news or magazine style websites, or organize your posts through detailed taxonomies, this plugin can significantly improve your daily publishing workflow. It is a simple but powerful solution for anyone looking to optimize category management, streamline content editing, and enhance usability in the WordPress admin area.</p>
