When a region is selected on the World Map, it could include region-wide descriptions.
This would allow estate managers to display an image and descriptive information for the entire region, similar to how parcels display in Places.
Maybe this could use the existing covenant as the description.
In addition, parcels listed in search should also be categorized and visible underneath the region's description.
This would not only benefit curated regions, but also benefit parcel owners. It would allow region owners to advertise their sim as a commercial shopping district, for example, while listing parcel owners with search enabled underneath that region's description when selected on the World Map.
This would make discovery via the World Map easier and would also make individual parcel discovery possible through the World Map.
