Description
GP Extender adds extra blocks and style options to the WordPress block editor, with spacing, animation, and conditional visibility controls for each page element, adjustable separately for desktop, tablet, and mobile. It serves those who build pages in the native WordPress editor and need more visual control, such as hiding a block on small screens or animating the entrance of a section, without installing a full page builder.

How to Download GP Extender
GP Extender is available for download here on Ultrapack. After getting the file, install it through Plugins > Add New > Upload Plugin in the WordPress dashboard. Activate the plugin and the new blocks and controls appear directly in the page and post editor.
Having these controls right inside the editor itself avoids switching between different plugins just to adjust spacing or hide a block on smaller screens. The result is a final page that is more consistent between desktop and mobile, without needing to rewrite the layout from scratch.
