While in reality I really can see any station in the future letting an independent contractor navigate a vessel into their working station unless it's fully automated under the stations control.
Putting that aside, as I really like docking, I think a docking assist computer would be great.
I don't want an auto docker, but it would be nice to have a computer that would bring up,it's display on the HUD as soon as you were in the no fire zone of a station. Giving you a recommended flight path into the dock entrance, even if it was a curve pointing around the other side of the station as you approached the wrong direction. Also like a current projection display, to estimate where your vessel will be if it keeps it's current flight path.
Top that off with as soon as you are through the entry hatch, for a recommended flight/glide path be displayed for your assigned pad, which would place you a little above the pad.
While I have never been any bigger than the type 9, I find it easy enough, though I do admit that when I first brought it, I flew out, turned around and flew back in (scrapping the shields) with it empty, just to test it's Clarence before stocking up with cargo.
