The ability to query feature layers in ArcGIS Earth by attributes is helpful, but often times a spatial selection/filtering is necessary. The existing spatial filter functionality for 3D object and point scene layers seems like it would fulfill my desired functionality, but it would need to be able to operate on 2D feature layers. Having this functionality would be helpful for non-GIS users to be able to select features of interest by simply drawing an area on the map and give them the ability to export to formats more familiar to them (KML) for sharing, etc.
