Great update
But ........
(you just knew this was coming)
A few things;
1. Adding questions - can there be answer field in the initial question add section.
2. If you edit the questions (to add answers etc) and then add another question, it clears all the existing questions data you have edited.
3. Can the default for part answer checking (in text questions) be yes rather than no.
4. On installation - please only add the templates to styles that have the "master style" as their parent - all the child styles will then pick the templates up anyway - otherwise you have loads of duplicate templates you don't need - and every change has to be made in every style, rather than them being inherited as they should.
5. Add a link to "allow" quizes from within the preview screen.
6. In the settings, can certain groups be set to default as "allowed" to take quizes.
7. In the quiz editing can there be a button in the "allowed to view results" to copy the groups from the "allowed to take" screen. I really can't imagine why I would ever allow a group to take a quiz, but then deny them the right to view the results.
