If their are multiple layers on top of each other and they all have pop-ups it can be confusing as to which layer is which. For example if I have a layer for "Fire Hazard" and a layer for "Landslide hazard" and the hazards in both layers are rated on a scale of 1-10 in places where these layers overlap you cannot tell which layer is which hazard severity. The name of the layer does not come up.
