The updated ArcGIS online map system now has the ability to add a map note when you do a search (See bottom picture). This would be nice function to add to the search results of the ArcGIS online applications (Web App builder or canned app pool). I have some web apps that users could use to plot muitple locations by search and I dont want them to have to use a map to do so.
This idea has been merged with 'Create Feature Here' Option From Search Result Popup in Web App.
