This is a great episode! The Lockbox gem recently added support for Action Text Rich Text snippets to encrypt them.  would it be possible to restore a version of an article record? Basecamp does something similar to this episode, where a Document has many Document::Version and the user can see an updated view of all the changes that have happened to the document. For restoring a version, you can open up a  Document::Version and click a button to "Make this the current version."
