When users are on a mission in its ortho view make a menu selection from the top left 3 lines below "All Projects" and add "All Missions"
Note: (I know you can click the name but that is not intuitive it would be nice to see the selection in the dropdown in the top left)
This will take users back to the missions in the Project. When I click the mission name I expected it to only show me missions with just that name (like a filter)
