Snapshots
     Snapshots enable you to see changes in your company data over the
      several weeks or months. A snapshot is one or more images of a dashboard or report, taken at
      intervals, which can be viewed sequentially to show changes over time.
  
    To see a list of your snapshots, expand the Snapshots tab on the side menu. The number of unread snapshots is indicated on the tab. You can reorder snapshots in the list, remove snapshots, and view their properties.
