- **Mapping Explanation** 
    - Add a simple explanation to a mapping (via a new tab in mapping details) so that non technical users can understand why and how a source and transformation is being applied.
- **Lock/Unlock mappings** 
    - Admins can lock/unlock a mapping to prevent non admin users from editing them.
- **BETA** - ask your Customer Success person for a demo
