I'm trying to think of the term that describes the design pattern of placing instructional text about a new feature inside a popover. It's like a coach mark, yet not in the traditional sense with a dark translucent overlay and with the text in a "casual" font, and it's not really an on-boarding experience, because the user may not be new, but the feature is. Sometimes such a popover could be the first of several for a tour or tutorial, but it doesn't have to be.
Does it have a name? It's driving me crazy! Thanks!
I've found and example of Google doing it, but tweaked it to fit what I'm looking for. What do you call the design pattern that describes what you see when a popover appears on page load (not hover or click) that describes a new feature?
