I love how easy it is for my team members who are not programmers at all but just have an idea what they want their app or service should do! It's great that you can add different features/ideas as long there isn't any other feature already added. New Co works with both users so this makes things much easier when validating our business models etc.. Also we've been able check if something will be possible by asking about user behaviour before adding those options into apps which saves us time later down-the line because of too many bad decisions taken early on :).
