What are the pins in Prototype mode

[FlatheadBeacon]

Hey all,

I'm in prototype mode and I see all of these small blue circles with a pin icon in them. What are they? When I click them they just disappear. Screen shot attached

They indicate elements that are fixed while scrolling, set with "Fixed position while scrolling" in design mode.

That makes sense.. Thanks Stuart!
