Sometimes, when you really care about disk space, or when your pad contents are extremely confidential or private, you might want to simply delete your whole pad, since people could still access your sensible content via the timeslider. And if there’s a need, there’s also a plugin.
ep_push2delete allows you to press one simple button and delete your pad. With all its contents and all its history of changes. Nice and clean. Without a trace.
Grab ep_push2delete from your /admin/plugins page.
