I think that I would like to use this system frequently If I was a teacher.

I found the system unnecessarily complex.

I thought the system was easy to use.

I think that I would need the support of a technical person to be able to use this system.

I found the various functions in this system were well integrated.

I thought there was too much inconsistency in this system.

I would imagine that most people would learn to use this system very quickly.

I found the system very cumbersome to use.

I felt very confident using the system.

I needed to learn a lot of things before I could get going with this system.

I found it easy to understand the compound pattern structure (the tree with AND/OR/NOT operators).

The filter feature helped me find specific match results efficiently.

I could clearly distinguish between matched, not-matched, and not-validated files.

The tool would be useful for analyzing student submissions in a real teaching scenario.

What would you improve or change about the tool? Please describe any difficulties you experienced or a feature you would like to see.
