Pointing the arrow is a nice simple understandable construct but how would that work when the object you point to is light years away from where you can see it in current time? Or may not even exist any longer.
Of course, the same problem exists in any other FTL technology. Where is the object you want to travel to NOW as opposed to where you see it now?
I guess you can fall back to the supercomputer everyone will have then that will do the calculations and take you in correct direction. Hopefully, if traveling in real space, no other object gets in the way during the transit. Flying through a star or into a planet would be life-ending for all involved! [lol]
