Hello Jerome,
My apologies for the late reply. I became a father to a baby boy in October last year and that has pretty much consumed my life out of work so far! I am just getting around to catching up with everything outside of work.
I did not work with React Native though it looks very interesting. We are debating if we should go fully native for our next release as we have complete integration with Forums, Quiz and Assignment submissions through Turnitin in the works now and we have definite plans to have separate versions of the app for tablets and mobiles. It seems logical to us to move to native apps for better performance as we have a lot more functionality to look at.
We haven't had a chance to strip out all the custom code which has delayed the release of our code on to Github, but I will be doing that very soon. At the moment the only way to see this on the phone is to download the app of the appstore or have a developer version installed through PhoneGap or Testflight.
Regards
Ravi
