After get Sharp-as-Night as companion (the best imho) I notice that his positioning is often extremely close to my character.
Other companions seems to have the same problem, and when we are in a mission that depends on a NPC following us, the distance mess is even worse!
Is there some menu's key that define our companions distance? If not, it would be a good idea create one.
I don't think Companions need to me so close to us. They could be at some decent distance to allow our characters move without being "blended" with them all the time.
The images show some examples:
