Revamp the way the "pathway" proceeds throughout the chart. Let's say that I've done the entire chart, but realized that the last 8 teeth were accidently charted one tooth over, so I would have to go back at where I have to re-chart. Instead of it charting one tooth and then resetting the path to where we usually start, it would be more helpful to let it continue charting anywhere we click, until the path is completed.
