Wonderful!!! I’m excited to hear it will be coming. My specific need would be for the check for understandings free response. I go through each question and want to give the students feedback about their response. It has the question, the student response, and an idea of what (per the AP curriculum) we should be looking for - just seems like a logical place to reply to the student.
I also agree that the students’ work would be another place to comment. The code.org platform is fabulous for learning but the ability to comment on specific lines of code or a pop out or ... something, anything ... would give me the ability to place feedback for congratulations or pointers for next time.
I’ll test it if you need a guinea pig!
