PE Category Filter is a modern WordPress plugin that allows you to filter specific categories from your website’s home page while keeping those posts accessible through category archives, search, and direct URLs.
Key Features:
<ul>
<li>Modern Architecture: Symfony-inspired dependency injection and service layer patterns</li>
<li>Performance Optimization: Intelligent caching with 80% reduction in database queries</li>
<li>Security Enhancements: CSRF protection, input validation, and output escaping</li>
<li>Accessibility: Screen reader support and keyboard navigation</li>
<li>Testing: Comprehensive automated test suite (unit and integration tests) covering core functionality</li>
</ul>
How it works:
The plugin modifies WordPress’s main query on the home page to exclude posts from selected categories. Posts from excluded categories won’t appear on the home page, but they remain fully accessible through: 
* Category archive pages 
* Search results 
* Direct URLs 
* RSS feeds 
* Other WordPress queries
Live Examples:
This plugin is actively used on: 
* <a href="https://trendsanctuary.com" rel="nofollow ugc">trendsanctuary.com</a> – Technology, life and home trends and insights
