This plugin adds variations to some core blocks and makes it easy to use blocks with dummy text and dummy images already entered.
It’s very lightweight because it just adds a “variation” of the core block.
<h3>Available Blocks</h3>
<ul>
<li>Lorem Paragraph</li>
<li>Lorem Paragraph (Long)</li>
<li>Lorem Heading</li>
<li>Lorem List</li>
<li>Lorem image</li>
<li>Lorem Columns</li>
