I'd like to be able to see audit logs for report changes (create, edit, delete) with delta as to what was changed when saved. For example I have a situation where we have dashboards that show different reports, and some of the reports are inaccessible - because they were deleted. Considering we had a holiday season and as we came back we don't remember doing it - it would be helpful to understand who did it to confirm if it's not needed anymore. Just one immediate example. Another one is that we're using the reports for creation of billing invoices (the split is based on a report) and one change in the report needs to be tracked with time as the historic data does not match up with what we see in the report anymore.
