It's frustrating for everyone involved when surveyors detect wrong answers in their post-submit "print answers" link, only to realize by then it's too late.

Such a feature would create more reliable and more user friendly surveys.

For assessments we need statistics about howmany people passed the assessment. (like an exam)
For auditing purposes we need reports how many points are scored per group as percentage of the total possible points. If possible shown in a spiderweb graph, where each group equals one line of the web.

Any question that totals to 100% gets a graphic representation in the form of a pie chart.
I tried to change the code to make it possible to choose a bar chart instead.
I did this because the pie chart is terrible to intepret when it depicts more than 3 variables. It sure looks nice, but it does not convey information in a nice manner: it flabbergasts.

The privacy note is too eye catching and should either have the possibility to be turned on/off or the possibility to change style from css.

There is as far as I can see, no css style for the privacy note making it hard to put to text in smaller size.

In many surveys what I needed to collect was year only or a year/month combination. Of course I could create custom combox but using a predefined question type is always easier.
