Metadata at a Glance: Instantly see Coordinate Reference Systems (CRS), bounding boxes, and feature counts. Attribute Inspection: Preview the data table associated with your vectors without leaving Finder. Privacy First: All processing happens locally on your Mac. No data is ever uploaded to the cloud.
