I like the way you split up your usability test into sections. I found this to be a very helpful way to keep the usability test organized. It is also very helpful how you have provided sub questions, within each major question. This makes the usability test easier to complete, and makes it seem less overwhelming to the user. Additionally, the subquestions help you, to ensure that you can get further detail out of the person taking the usability test.The formatting looks good, underlining is effective.

(Late review because of revision)

I think you did a good job on the revision. You seem to have captured a very typical use case for a user of the system, which is what we are designing our project for. It also gives us focus on what to include in our documentation and presentation, particularly tricky little things like the location of those buttons. Overall it seems the functionality of Dragonfly seems to be fairly easy to use, but there are just so many things you can do with it, it’s difficult to find your way around at first. But once you get there, it’s intuitive.
