As we all know, right now: "Layers are always displayed on top of a basemap and feature layers are always displayed on top of heat maps and tileset layers (map, imagery, and tiles). Depending on the type of layers you have in your map, you may not be able to move them all up or down. For example, if you have one map layer and three feature layers, you can reorder the feature layers, but you cannot move the map layer on top of them. You cannot reorder a KML layer or a basemap."
Any plans on changing this ordering limitation in the next AGOL release and being able to put any layer/service in any order?
What do you guys think? Wouldn't that be great?
