Two things I think would improve the experience for traversing the landscape when you're roaming around:
1) Accessible map screen when you press the track pad (PS4) - you could map it to the "O" button... The areas are pretty massive = especially the Moon level based on my exploration last night. I had no idea where I was after a while and having a quick overview of the area / key locations and landmarks etc would be great
2) Fast travel between zones. I know they are designed to all link to each other and to encourage roaming around... however given the size of the levels mentioned above it's a bit annoying having to go all the way across a level / or have to go back to Orbit and then come back down again...
