Block that displays a list of selected Posts and Custom post types. No stylesheets or scripts are added in the front-end.
<h3>Usage</h3>
The block can be found inside the blocks inserter menu under the Melonpan Blocks category. 
Once added in the post you can edit its settings on the Editor sidebar under the Block settings panel. 
The block renders dynamically. This means it doesn’t save any content in the Post content, it renders the content when the post loads.

Adds meta boxes to all post types and allows you to convert the post type of the current post you are editing to a different post type. This very useful when doing an import from another site into one post type that then needs to be filtered into different post types or even to fill dummy posts throughout multiple post types.
Please refer to full documentation at https://github.com/voceconnect/post-type-converter/wiki.

Post Type Converter
