Project Snapshot/Comparison Report Features

Having the ability to stamp/save/take a snapshot of a project at specific points would be immensely helpful for the newly implemented plan versioning feature. Specifically, having the ability to generate a report that shows just the edited takeoffs (i.e. these reports would only show takes offs that were added, deleted, changes in verbiage, properties, quantities, etc.).

I think projects that have snapshots should have an expandible/collapsible caret menu where they are stored in the 'Open Project' page. They can be labeled with revision names (e.g. 50% SD, 100% DD, 90% CD, etc.) and previous snapshots are viewable but no longer editable.
