For Agile planning, the existing "Backlog" view in a JIRA Scrum board is extremely limited and almost useless for real planning (though it is just barely better than nothing).

We need a hierarchical view of Epics and Stories in one page so that we can

• manage both epics and stories
• be able to actually read the Epics (current left hand column is way to small and not even an expandable panel),
• easily see the hierarchy,
• easily be able to select fields to show on that list,
• have editable inline fields on the view,
• drag and drop prioritization
• ability to move stories between epics,
• etc. (hint: see VersionOne, Rally, TFS, Thoughtworks, etc, etc, etc, etc).

There is a reference to hierarchy in the community questions but there is no response from Atlassian. Its very old and this is clearly a huge miss in my opinion.
