Add summary count to Epics

When using the Agile Scrum board in Jira, I want to see the “summary count” of the remaining open issues, in the collapsed (and expanded) view of the Epics tab.

To calculate the “summary count” I’m referring to, use this math…
“Issues” – “Completed” = “summary count”

Problem: Right now, I need to click on each Epic individually to see the summary count in the Backlog view and cannot get an overview of the summary count of all Epics at a glance.

Request: Add a summary count numeric field exactly like the current ones, but at the top between the Epic name and the colored pull-down option/arrow (to the left of the colored pull-down). See mock-up below.
This would make this information available without clicking on Epics individually. The summary counts would also be visible without having to expand the Epics themselves, giving you an overview of how big each Epic is at a glance. This would be extremely useful when managing/grooming several Epics at the same time.

Please look at attached image for an example of what this would look like…
