Hello, dear khan developers and staff.
I would love a version of khan academy for mobile which is low bandwidth, small download mainly focused on text and knowledge articles and self-testing, rather than videos -- as a supplement to the main site.
I am not somebody who pays for big data plans on my mobile, and I'm sure many cannot afford large mobile data plans.
I find the current mobile site is mostly like an app version of the main site which is fine, but a small version which could be read and have self testing would be great too someday.
