@JTFP_GEO is there a specific Instant App you'd like to see this capability added to? 3D Viewer, Attachment Viewer, Media Map and Slider have the full screen widget now.
Not the OP, but it would be helpful for us to have it added to the Basic Instant App. I'm working on a map that we want in a smaller window on our website, but it would be great if viewers could make it full screen to better explore the map.
