Q031 - Q040: Most important software development related topic? - Ask in 1 question for prioritized list and offer up to 10 input fields

I had the impression that it took me by surprise that more and more text fields were revealed when answering this question.

I would suggest to squash those 10 questions into 1 and offer up to 10 input fields for a prioritized list. Some hint that participants may fill out as many form fields as they like would be an alternative, I think.
