I know we can move reports to the private folder to hide them from others, but I think it would be nice to have the ability to run a nondestructive or view only style report. Similar to SFDC, you would be able to edit an existing report by changing anything you'd like without altering the original saved version of the report.
Maybe something as simple as the ability to create report drafts. Maybe for reports in the Analytics section, there is a "Save Changes" button instead of auto-save for previously saved reports. It would just be helpful to eliminate the need to create several reports with minute changes just so you can access each version quickly without ruining the original.
