Companions can be a huge help but the fact that they keep wandering around, commonly out of sight when you most need them. Perhaps reduce the frequency of running around that they do when they are not in combat.
A call function would be incredibly useful as has been asked for in several posts, however could you please get them not to stand directly in front of you when you are trying to craft, harvest, etc. (its like trying to eat with your cat or dog watching you) standing off to 45 degrees when they stand there staring at you would be helpful. If you turn to face them they could move out of your direct line of vision after 1 to 2 seconds
