Post Pruner adds a screen under Posts > Post Pruner that groups your published posts by age so you can quickly find and act on stale content.
Age buckets — browse posts that are 1, 2, 3, 4, or 5+ years old, or view all aging content at once.
Sortable dates — sort by the date a post was created or the date it was last modified, so you can find posts that have never been updated.
Age mode toggle — choose whether age is calculated from the post’s published date or its last modified date. Preference is saved per user.
Never updated badge — posts that have not been edited since they were published are flagged with a “Never updated” badge in the Modified column.
Single-post actions — edit, set to draft, set to private, or trash any post directly from the list without leaving the screen.
Safe by default — actions move posts to Trash (recoverable), never permanently delete them.
