    Add clustering and heatmap functionality to the ArcGIS Online webmap viewers and application templates.  Both are available in the new Esri Maps for Office addin.  A similar implementation for Online would be great.  This would help novice GIS users toleverage the ArcGIS online webmaps and provided better visualization tools for point data added via shapefiles, CSV, TXT, and others.
