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!
New Info:
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?
