Duplicate Order Avoidance
It is better to prevent duplicate orders than to clean-up later in a long encounter.
One way to anticipate possible duplicates is to note the visual cue appearing when orders are being lined up for signing:
The small purple square to the left of the new order contains a digit reflecting the number of possible duplicates. Clicking on the number brings up a list with buttons that can be used to discontinue duplicates right away.
