With GDPR, companies are required to provide justifications for all data that they collect. In Salesforce this means being able to identify why all fields in the system exists, categorize fields as PI, and provide business justifications. The ability to keep a list of current fields in a production instance of Salesforce that includes alerts when new items are added, or ability to sync that list out to another tool like Smartsheet, where other business users like a legal team would have visibility, would be incredibly useful.
