Add additional script options. Currently their is only 3 available. It is very difficult to chart just one specific quadrant. It always wants to just jump back to "where it left off." It would be useful to have 1 script available for full mouth charting, and 4 additional scripts available for for each Quadrant of the mouth (LR, LL, UR, UL). Another useful button would be an "undo" button. Rather than pressing "clear" and deleting everything in that box, it would be more useful to have an undo button to just go back and delete that last number or input.
