I don't have particularly strong feelings about this, but I would like it if the radar display had some indication of how aggressive a ship (NPC or real player) could potentially be when you see it as it now only lights up when it is attacking you. I could imagine that ships that recently attacked another ship (talking about innocent targets here, not wanted ones) gets an orange or so marker in the display. This marker could last just a few days but it would be enough when you see several ships to give you some indication of how safe you are. Of course it wouldn't be failsafe, but that wouldn't be neccessary to me.
