Right now, when marking a solution on an image poll/picture question, the cursor stays the same, it would be helpful to change into a cross hair as you're dragging over the area. It's hard to tell where your rectangle starts. Could other colors other than yellow be added when an instructor marks the solution?
It would also be nice to have the ability for students to freehand draw or use shape tools to select their answer. Another alternative, make the selected area that student clicked a bigger circle (the dot is very small) making it easier for the instructor to see where students have clicked. Each time I demonstrate the image poll from the instructor and student perspective these questions come up. I had a training session today, so it reminded me to make this request. Thanks for your consideration.
