If I create a survey that is not anonymous.
I send invitations via email.

I want users to save their survey and come back later without having to create some user and password information.

All they should need is just their token to come back and go on with their survey.

I know that there is the option of answer persistence but this does not work if I let the useres answer the survey questions group by group and it is not intuitive for the users.

There has to be a explicit button for saving the survey unless users would not think that there is the possibility for saving the survey and come back later. Especially if they are not really computer experts

Best regards

There are surveys we take that require some degree of geographic information to be submitted.

Rather than ask novice/general public users to use a GPS and submit coordinates (which invariably end up incorrect), we would like to have them use a map-style interface like Google maps, where they can drag and drop the pin where they were when they saw what they are reporting, and then have the question type save the latitude and longitude of their dropped pin.

From time to time we encounter the next situation: we have a multiple selection question, we will like to be able to know when someone has selected all the options so we can direct them to another question.

For that we suggest making the 'All of the above' option automatically kick in if the participant checks all other options.

Allow hiding Welcomepage (when you are linking different surveys together) or different Endpages (e.g. respondents get suitable redirection).

In a field declared as a number field it is not possible to fill in numbers with a "," as decimal separator even if the language choosen should allow this (e.g. German). This can cause a lot of confusion to survey participants if they get an error when the number ist typed in correctly.

For assessments we want to attach files to a question as evidence for the answer.
