There were some useful features in the old DataStax Academy site that I don't see in the new one:
1. The ability to play a video at 1.25x speed
2. The buttons to quickly go 15s forward or backward in the video
3. The ability to see which questions I got wrong in the quizzes. Now it only shows the percentage, e.g. 66,7% correct, so I don't know which question I got wrong and what topic I should revisit to improve.
Will these features be coming back?
