Enable Excerpts for Pages
Adds the Excerpt box to pages, which many themes and SEO plugins can use as a summary.
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.
Previous and Next Post Links Below Posts
Adds links to the previous and next post at the end of each blog post, for themes that do not show post navigation.
Show Excerpts Instead of Full Posts on Archives
Shows a short excerpt and a "Read more" link for each post on the blog page, archives and search results, for themes that print the full content of every post.
Show the Featured Image Above Post Content
Prints the featured image at the top of single posts, for themes that only use featured images on archive pages.
