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
Two wrongs don't make a right. There is absolutely no reason for having a straight line in any view, so why didn't you take it out of all views rather than putting it in the remaining views?!?
As has been said, no one asked for this, so why waste time doing something that 95% of people don't want!
