HGW Better internal link search for Block editor

HGW Better internal link search for Block editor improves the default internal link search inside the block editor by adding a post type or category selector to the link popup.
This allows editors to narrow down search results to specific post types such as Posts, Pages, or custom post types.

Features

• Adds a clean “post type and category filter” dropdown above Block editor link search results.
• Works with all REST-visible and publicly queryable post types.
• No database queries or custom endpoints — fully uses WordPress core APIs.
• Loads only inside the editor, never on the front-end.
• Lightweight, fast, and compatible with all major themes and plugins.

1. Upload plugin folder to the /wp-content/plugins/ directory
2. Activate HGW Better internal link search for Block editor through the Plugins menu.
3. Open any post or page in the block editor.
4. Click the “Link” icon inside a text block.
