It's a real pain not being able to share survey contents (inc logic) with a wider audience. Especially with plans being limited to 3 to 5 users. Also see this question.
I've spend a some hours to make something that takes in survey definition json files that can be downloaded through their API or their Request data function and generates a somewhat human readable overview. This overview could then also be saves as pdf.
