It would be great to be able to create a duplicate layer in an ArcGIS Online web map by clicking "Options" and then "Duplicate." Often, I find myself adding the same layer over and over and reconfiguring similar symbology, pop-ups, and labels when I could just duplicate the layer and make a few small changes instead. Note: I'm using the new web map viewer (not the classic viewer, which does have the "Copy" capability).
Please forgive me if this is already a capability, and I just haven't been able to find anything about it.
