Revolutionary educational software. A constructive criticism for the Mobile app and Ipad app - a landscape view would be nice. When I participate in discussions and I have to set my IPad down to type in landscape, I have to read off the screen in portrait view, so I have to tilt my head to the side or somehow balance it. Even still the response box senses the landscape orientation, but the question in the background doesnt! Its awkward... Other than that, which is a quick tweak I imagine, it has really helped me get the most of the course Im taking.
