We received some feedback from an individual who watched the Walkthrough Tutorial found at https://www.youtube.com/watch?v=FIpUJuhDMc8 .

One point they mentioned was that:
"Generate random values for the text field is both an unlabeled icon for a unique feature (hard to guess) and only visible on hover. I couldn't see what you were talking about the first few times you mentioned it."

I would agree with them that for a new user, it is very hard to discover this very unique (and powerful) feature when it is not visible to the naked eye (requires not only hover over the row, but then hover over the icon to get the tooltip text).

Attached a potential proposal to surface this button/icon more and treat it similar to how we treat assigning a data context to a page. To be discussed before we move forward on this though.
