Minimum Size for Featured Images
Stops posts from being published with a featured image smaller than the size you set, such as 1200 by 630 pixels, so social previews and hero images never look blurry.
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.
