We use reports often to tailor Aha data for different audiences. Recently, those audiences have been looking for summaries of how the data in that specific view has changed over time.
The changes can be pieced together manually by looking through the /audits section or manually reviewing the History of each individual Feature or Requirement in the report. We haven't found a way to make either of these practically feasible.
This idea is to bring History to reports, so that from the Report itself, there could be a way to access a History view just like the one for Releases, Features, requirements, etc; but showing all changes to the data captured in the report.
Ideally this History would be accessible to all roles, but if it needs to be limited to Product Owners and Contributors, then I'd request that it be exportable so that there's a way to share a summary of changes with stakeholders.
