Tim Hunt‘s posted a great synopsis of a few usability changes to the Quiz module in the Moodle Forums and now is asking for feedback (votes) through either the forum or the tracker for those who are interested. The improvements aim to remove some of the interstitial clicks required to start a quiz, to make relevant information (whether the quiz has a password, time limit, limited attempts) earlier in the work flow and overall to remove some of the extra clicking that’s required to navigate to start, within, and once a student has completed a quiz.
There are 7 total UI tweaks part of the Epic tracking improvements. You can find a link to them all and see their progress here: https://tracker.moodle.org/browse/MDL-46090.
