WGTNico: The white line is here to stay in WGT as it is an intended feature especially since the line is available on every other putting view
@Nico: I think the people have spoken. It seems no one but you want this white line. There are many white lines. Some of us have chased them down the highway, some of us have put them up our nose but none of us ever had them on a green. Maybe if we knew how to use it or an explanation of why it is there other than it's an "intentional feature" we could change our minds. But, if it must stay, then we should have the option of turning it off like we have with other things we do not use, just sayin
Cheers
