HTML5 Minisurvey - add additional features

I have a minisurvey at [login to view URL] - I want to add some additional features to it: - I want two version on it which will be randomly presented to participants at an even rate (Test.a and Test.b) - I want it to save answers automatically after participants answer the questions - On the Questions page I want to have a) a Multiple choice Question widget a2) multiple question widget with Else option (small input textbox here) b) a scale widget (similar to the one on the first tab) - some minor debugging in the already present widgets, set new font etc.
