Thanks for your quick reply. We will disable the Find Courses feature.
Happy to share our customizations. In addition to customizing the graphics, we are also changing text instances of edX to our company name, changing the Terms of Service to our own, and hoped to allow students to find and enroll for courses on mobile. We would like to enable facebook & google+ login, integrate segment, and get push notifications running with parse.
We look forward to the ability to offer students more than just video on mobile -- we hear that's coming in the new year too.
Thanks for the great work on open edX,
Anna
