First, thanks for all the work you do for the Moodle community. I mostly lurk, but I do see.
We currently use Realtime Quiz on our 1.9 install, and are in the process of upgrading to 2.4. As I understand it, your updated version of RTQ lets you see what each student answered on each questions, but I get the sense that it does not aggregate their results. If not, do you have any plans to make it aggregate student performance on a quiz? Better yet, do you have any plans to link RTQ results to the Moodle grade book so that teachers could more easily use it as a real time testing device?
All the best,
