I second this. Especially with long surveys it is a pain to have to test from start to end (of course in some cases there is no other way, because of conditions or expressions, but this is another topic).

I would like to add the option to prevent randomization of answer options. Especially in long lists it can cost you a lot of time to check wether all items are there or not. For first checks, it is important to see if all items are there. Later you can check (fairly easy - usually you see it after the first 2 items in the list) if they are randomized.

Very good. but then: not only on question level, but also on group and survey level...

Bump.

It would be nice if comments could be placed on the questionspage instead of collecting them via phonecalls and emails.

Not done for this (done for comments on current response)

I think it's a plugin task here.

About :

To get to certain parts of the survey it would be good to be able to skip conditions and validation rules and skip back and forth through the survey.

Set index as full, i always use like this during test.

We also had a need for a review feature so we implemented this as a plugin for one of our customers. If our plugin is active, an additional comment question gets added to every survey page automatically when activating the survey. There is nothing else you need to do manually.
People can then test the survey and comment on different details. You can export these comments for review and adjust your survey as needed.
Later you simply deactivate the plugin, activate the survey once more and the comment questions are gone.
Pretty straightforward to use...
