When you are creating a survey and you want to rearrange the order of questions, you don’t have re-write them. 

Moving questions is easy, in the map view simply mouse over the question you want to move and drag & drop it into a space in the survey. 

In list view you can also move text cards and questions, by using the card list. Click the move card icon next to the question you want to reposition, and draft the card to wherever you'd like it to sit. 

You can keep changing the question order until you purchase the survey.

You cannot move questions in the list view, you’ll need to switch to the map view to be able to rearrange your questions.
