Issue Hierarchy Tree by Katassr

Issue Hierarchy Tree renders your issue's full ancestor-to-descendant hierarchy as an interactive visual map, right inside the Jira issue view - not just a flat list. It works with Jira's unified "parent" field, so it supports both company-managed and team-managed projects, including custom Advanced Roadmaps hierarchy levels above Epic. Blocking relationships ("blocks" / "is blocked by") are drawn directly on the map, including links to issues outside the current epic or project. Nodes load on demand, so the app stays fast even on projects with hundreds of issues. The UI automatically matches your Jira light, dark, or system theme. Currently available in English only.
