In the various locations that JIRA lists issues (e.g. viewing the issues in a Release), the issues are listed in a "flat" manner, regardless of the issue type. Epics, issues belonging to an epic, and parent / sub-task issues are all displayed as the same "level", and are intermixed. It is not possible to see these relationships.
Is there any feature of JIRA, or recommended plugin, that offers the ability to see their relationships? Ideally, this would alter the existing listing views in JIRA (i.e. on the Release listing page) rather than providing separate functionality elsewhere.
