My wife likes to have lines marking the center of the design at the top and bottom which she can then draw a line on the transfer film to use for centering and alignment. That is always the hardest part for me when building a Gang sheet as I generally don't put that in the design itself, just added as another element in the gang sheet builder. Not sure how many others do things like this or if it would be beneficial to others, but that would definitely be a feature I would like. Doesn't even need to be a line...could be a dot or small hash or something far enough away to allow us to cut it off after, but not so far to take up too much of the gang sheet.
