Features requests: global settings, quiz copy, statistics for all quizes

Hello,

I would like to use this plugin for an academic course instead of using moodle.
Here are some basic features which I think can help me and others:
1) Global settings. For example, to set to keep the statistics for all quizes.
2) Copy a quiz – it would be nice if I could copy quiz that was just created with “good” settings, and edit it – instead of starting from scratch.
3) After a course has ended – I would love to see overall statistics for all users for all quizes.

I would be happy to know if it might be possible to implement some/all of these features.

Many thanks upfront,
Tal
