Hi Imemine,

Thanks for sharing this! I definitely agree that a graphical representation of activity time would be helpful for many learners and teachers.

I'll share this feedback with the appropriate team so they can consider this for future updates. However, since we're a very small team and the developers are already working on a couple of big projects, I'm afraid I don't have any estimates as to when something like this might be implemented.

Thanks again! Please let me know if you have any additional questions or suggestions!

This is a great idea. I hope we'll see it on Khan Academy as soon.
