THANK YOU for making it possible to give feedback on Assessment questions. I really like that it is rich text too so I can emphasize things or clearly mark where a mistake occured. I also (as a world language teacher) love that I can leave an audio recording as feedback!
For longer text responses though, it would be nice if I could annotate/mark up an answer like I can from the iPad app when students submit documents via Assignments. My work around currently is having to copy their answer and paste into the feedback box and then make corrections there. It works, but it is very time consuming.
