Just random stuff I'd like to know-

1) When you are flying around, a ship that shows up as a red dot/arrow is hostile, and blue is another player. What is white?

I see a ton of ships hanging around at spaceports, POIs, outside of bunkers etc that are white. I can only guess that they are player ships, but the player isn't online or in them?

​

2) If I am running around on a planet, do I come up on a players radar in their ship? Or does it only pick up ships?

​

3) Do grenades work? I remember previously you could select and throw them. Either they have changed the key bind for it or it doesn't recognize you have a grenade? Anyone know what the actual key bind name (not what you press; the name) for it is?

​

4) Is it possible to unlock a player ship? For example, if the 'white' ships above are MIA player ships and they are closed up/locked...is there a way to get inside?
