I want to show a layer upon returning/revisiting the base layer but only after all markers have been visited. The scenario would be: when returning to base layer from another layer in the same slide, if all markers have been visited, then show layer "X".
I have attached a simple example. I want for the layer labeled home to show only after I return from viewing the other layers that were triggered from the markers which will now be in a visited state. Is this possible?
