Hi Ameerah,

Thanks for the suggestions, we really do appreciate feedback! Since Khan Academy is a very small, non-profit team, they do have to prioritize on what features and content do get implemented, but input from the community is always welcome. You may want to check out this thread and vote it up and/or leave your thoughts :) That way, the team will be able to see the popularity and demand of certain content.

Again, thank you for the feedback!

Allison
