Find Reports More Easily While Adding or Editing Dashboard Components
Instead of just searching by report name, find reports in the dashboard component editor just like you do on the reports tab. Flip through views (like Recent, Private, and Public) and folders. Of course, you can still search by report (and folder) name. This feature is new in Lightning Experience.
After adding a dashboard component by clicking + Component, the Select Report window opens and prompts you to select a source report.
