End of sprint reports are available in Jira. In Confluence, however, once the sprint ends, the Agile gadgets are no longer useful. It would be great to persist these (right now, your best bet in Confluence is to take a screenshot of your burndown before you close your sprint).

Being able to fix a point in time on the Agile gadgets in Confluence, for example, so you can review them months later, would be great.

This is something a lot of our clients would use. JIRA filtering is very powerful, and a lot of our enterprise clients want to have "point in time" reports, actually more than they would want dynamic JIRA issue lists to show up in Confluence. The report blueprint falls short in that it's a standalone page and can't be customized.

Think of meeting notes, or stand-ups. A static report would allow one to use a filter to identify issues to discuss in a meeting, and then use that same filter to insert that list into meeting notes stored in confluence.

Hello - thank you for sending in this suggestion! Unfortunately, we do not have any plans to implement this in the foreseeable future. In order to set expectations correctly, we're closing this request now. If you'd like to describe more how this would help in your own use of Confluence, we may be able to provide better guidance.
Thanks again for your idea, and please feel free to submit more!

Regards,
Confluence Product Management

The only options available is the Jira report blueprint. This generates an overview of issues that can be made static. See screenshot.
This report has no option to add other fields to the overview.
