As you can see, the Report Manager shows a folder and list of available reports. From the toolbar, you can create a new report, duplicate the current report, delete it or create a 'workspace report' from the current report.
When creating a new report, the Visual Query Builder will start so you can create the query the report is based on, after that, go to the Report tab to enter the Report Writer. Don't forget to use the Save button to save the report to a file.
