Easily configure posts to expire at a certain date and time. After posts expire, they can become drafts, private, deleted, or in the trash. Works without Cron enabled.

If you use the WordPress admin area on a mobile device, or have cats sometimes walk across your keyboard it can be good to have a fail-safe confirmation before permanently deleting posts from the Trashed items. 
This plugin adds simple JS to the admin area to do just that.

Trash Fail Safe

Require confirmation before deleting items from the Trash, or emptying the whole Trash. Protects against accidental clicks.
