I just toyed around with it and can think of a time I'd actually use it.
On those long putts, where I like to drag the aim marker beyond the hole just trying to get a read on what happens after the hole. Since I like to putt from the reverse view, often find that I forgot to drag the aimer back into view for the reverse view putt.
Now, instead of having to change views again to drag the aimer back into view, either that or trying to use the mini map, which can be fun to get the aimer back in view. Now I can just click anywhere in view to bring back the aim box.
Where I do find myself destined to do it unknowingly, is off the green. Aiming a drive and clicking the screen somewhere along the fw or worse, wayyyyy OB lol.
This could, however, explain those few times where my avatar has been facing back at me. Like he wants to hit the ball out into the real world through my screen. ;-)
