Web Map viewer Save button to indicate new unsaved changes

[Anonymous User]

In ArcGIS  web map viewer, the save button does not indicate that pending changes to the map have not been saved.

• Web map save button before changes:

• Web map save button after changes:

In Web AppBuilder for ArcGIS and most ArcGIS  configurable templates, it is possible to see if there are unsaved changes in your map/app.

• WAB save button before changes:

         

• WAB save button after changes:

         

There is even a message to let you know that your changes will be lost if you close/refresh the browser page!!

Could we also have this for the web map viewer?
