Seems like a basic feature, maybe i'm missing something.
I can see how branching works, but there is no criteria attached to it.
Please rate your experience question would be a 5 star rating question. If response is below 3 stars, I would like follow up question to be available to explain why (but not visible unless the rating scores low).
I see in text fields a "restrictions" options that allows you to enter a number greater than, less than, etc, but it doesn't seem to relate to anything (not eve sure what it's there for). Like I said, seems like a simple feature built into any survey application... so i'm really hoping that Forms isn't "too" simple.
