Most of the value of snapshots are explained in the versioned-snapshots README file, but the major takeaway is that this history viewer will show you the changes that have happened to objects in your $owns tree as if it is native history to the owner object. In other words, it helps authors to see the answer to the question, "What happens when I publish this page?"
Further, since each snapshot provides a timestamp, it is possible to view a page at a time when a given owned object was added or changed.
Provides a drop-in replacement UI for versioned-admin that adds snapshots to the history view.
WARNING: This module is experimental, and not considered stable.
Just add the SnapshotHistoryExtension included with this module to your dataobject, and a "History" tab will be provided to its getCMSFields() function, offering a list of its snapshot history.
