Ability to drag/drop columns or filters in the dashboards irrespective of the dashboard type, i know this works in pivot chart today. This helps user experience with minimal user clicks.
How would you do that exactly? In the pivot table we have all fields listed in dedicated areas so it's straightforward, but how would that work for a pie chart or a bar chart?
You also want to have the list of the fields exposed by the datasource, and be able to define filters on the fly or change what column to show value of? So basically you want a "pivot chart" component?
Or would that ability only be available when creating a new portlet definition?
