Meta Box Blocks Addon v1.7.0

Meta Box Blocks Addon GPL Overview:

Since version 5.0, the block editor (Gutenberg) has become the default editor in WordPress. This block editor allows you to write the content and live preview it in real-time. In other words, what you write is what you will see on the front end. Gutenberg supports a lot of blocks for content creation. But it’s never enough. WordPress developers still need to create custom Gutenberg blocks for their specific piece of content. And that’s where MB Blocks can help you speed up this process.
