As a user, I'd like that inside the Epic it defaults to display only open issues and have an option to display completed issues.

Right now, it displays the entire list of issues, completed and non-completed. There are cases where this list gets very long and cause delays to load the entire page so I can filter the issues that are done.

It would be great if it defaults to display only non-completed issues and give the option to display the completed one through the check-box.

Currently, it loads everything and I have to wait to load the page so I can filter to hide the completed issues:
