Hi @Vladimir Strange. Happy Monday
As Chat works like a Chatbot interface, respondents can't scroll to the next question even if it's not a required question. This means the respondents will have to interact with the question in order to move on. Be assured I'll forward your suggestion to the product team - hopefully this will change in the near future. =)
Let us know if you have any further questions!
I also need this feature. I see no harm in you allowing the user to press “enter” and submit with nothing in the input box when a question is not marked as required.
Otherwise to improve the UX you should indicate that all chat questions are required in the builder so I don’t have to scan your site looking for the magic keyboard combination I’m suppose to know to skip an optional question.
