I am in the process of trying to do some major clean up of unused reports.  When I attempt to delete a report, if the report is referenced by a Dashboard, the message that appears is not helpful at all...other than telling me I can't delete the report because it is referenced by one or more Dashboards. It would be great if the message could tell me which Dashboard(s) the report is referenced in.  I know I could create a SOQL query and utilize some other tools to gather this information, but this seems like it shouldn't be that hard.
