I can't believe that we can edit or delete in reporting, but on the dashboard. Once you screw up 1 setting of 1 widget, you are stuck with it forever on your dashboard or you need to start all over with a new dashboard and hope you don't screw up.
Why is the function there for reporting but not for dashboards which people use way more than sending a report on a schedule.
Please make this a reality. Dashboards are useless if you can't customize them and not everyone has the skills to custom-code when the widgets that will get the job done are already there.
