Agreed, lack of edit button is a major step backwards.
I tend to use the vertical lines on the pin board as a guide for the saw plate to stay parallel with, rather than aiming to remove them. On the pin boards, as I need all of the pencil on the end grain to stay visible, its just easier in my head to leave the verticals too.
Renaissance Woodworker did a nice video on 5 exercises to improve your sawing on his YT channel. It seems to work along the same lines as sports training. You never go straight in to competition, you first practice, and then you warm up.
