Private Editorial Notes in the Block Editor
Adds an "Editorial notes" panel to the editor sidebar where writers and editors leave internal notes about a post, such as sources or open questions, that never appear on the site.
Snippet Library
Content snippets for WordPress
Snippets that add to or change your posts and pages: reading time, author boxes, “last updated” notes, content after the post or after a paragraph, and excerpt tweaks. For bloggers, publishers and anyone who wants richer posts without editing theme files.
Show Content to Specific Roles
Adds a [show_to] shortcode that reveals the text inside it only to users with the roles you list, such as editors or customers.
Stop Authors Editing Posts After They Are Published
Lets authors and contributors write and submit posts as usual, but once a post is published only editors and administrators can change it, which keeps approved content approved.
