Hi Russell!

Thanks for sharing your thoughts on the features that could be added to the teacher dashboard to provide you and your class with a better experience. We are always working to add features that improve our site, and we love getting input from our community.

I've passed your feedback along to the team and it will be part of our conversation as we plan the future of Khan Academy.

Thanks for helping improve Khan Academy!
