Plenty of very useful features

For a free plugin, it packs a really good range of functionality without affecting site speed. You can choose which features you want to turn on/off. It enables the Glutenberg editor to become a really powerful page builder, and also adds a lot more useful elements to blog posts. I particularly love their Review Snippet for SEO, and the Posts Grid which can display the latest posts from any specified category. 5+ stars, highly recommended!
