I would like to be able to sometimes turn the compass on and leave it on (walking and/or rover) while at other times it could be annoying
Those first few minutes on a planet though, it would be nice to be able to leave it on
I could even vote for a 3D mapping tool as an end game item that could be used to connect underground tunnels from one base to another
Something where you had to explore so much of a planet, placing beacons etc until the system could be totally useful planet wide, but you could expand your network of knowledge as you go
