Footnotes Shortcode
Adds a [ref] shortcode for footnotes: each note becomes a numbered superscript link, and all notes are listed at the end of the post with links back.
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.
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.
