Just wanted to share a few functionalities that I enjoyed in Google Earth that doesn't seem available yet in ArcGIS Earth (Version 1.5 Build 1704). Thanks for your consideration!
1. ability to edit a draw feature (point, line, polygon) from the map vice the TOC
2. location units: degrees decimal minutes
3. ability to copy, cut, and paste individual features in the TOC
4. ability to view some attribute data for draw features in the TOC
