It is a popular plugin for WordPress that allows users to easily make a copy of a post or page, and then edit the copy without affecting the original.

The recommended usage of this plugin is mainly when you want to create a new post or page that is similar to an existing one. Instead of creating a new post or page from scratch, you can use the plugin to create a duplicate of the existing post or page and then edit the copy as needed. This can save a lot of time and effort when creating similar content.

People are taking advantage of this plugin in various ways, such as:

• Creating draft copies of existing posts or pages for editing before publishing
• Creating different versions of a post or page for A/B testing
• Creating a backup copy of a post or page before making major changes
• Creating multiple versions of the same post or page in different languages
• Creating a template for similar posts or pages

It’s worth mentioning that this plugin can also be useful for users who manage multiple WordPress sites, as it allows them to easily duplicate content across different sites.

The plugin also allows to customize the suffix and the prefix of the title of the copy, and to choose the elements to copy like the excerpt, the featured image, the custom fields, the comments and the post format.
