Move Posts in a Category Back to Draft After a Number of Days
Automatically unpublishes posts in a chosen category, such as Jobs, Offers or Events, once they are older than a set number of days, so stale listings disappear on their own.
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.
Unstick Sticky Posts Automatically After a Few Days
Removes the sticky flag from posts a set number of days after they were made sticky, so featured announcements do not stay pinned to the top of the blog forever.
