Laser Designation or Range Finders
I know that there is a mod that allows you to laser designate objects in the distance but we should have it in vanilla, a laser designator that gives you the range of the object in front of you. A small one for short distances (20 to 30 km) and a large one for 100km+ distances. make it like a jump drive that recharges after it's used. It'll be such a handy tool especially if you're flying towards an asteroid, so you should know how far it is and when will you start breaking.
