I'm not understanding why variables are only tied to "Question". "Multiple Choice" is also a question, but there's no variable option is provided. I would take input to identify a single variable name, but then place the value input underneath each option. However, I'm not seeing any advanced way to make any further decisions with the selection options, other then branching that done with connections. This could be a good tool for younger, or new, authors that want to get a feel for the fundamentals.
