It would be helpful to have an option in the search widget to set a default layer to search from instead of defaulting to all layers. In most cases our users will just search an address but want the option to search for our organization specific layers, but because the default all layer search takes so long to go through they are required to uncheck all layers and select the geocoder every time they open the viewer.
