Feedback for PE dry-run

[ChangUo79]

Hi, good work on the application. A few feedbacks that I have is that many of the example commands does not correspond to the actual command. One example is annotate 1 p/2 h/pink but the actual command is annotate 1 p/p2 h/pink. Many of the instructions were not as clear.

I feel that it can be further improved, even though I did not manage to go through all of the commands. Adding in diagrams will exponentially help the user understand better what they are suppose to do and what they are suppose to see after the command.
