Gantt and plans
The Stratify Gantt shows work items from several spaces based on a JQL, draws them as bars over time, and nests them according to the configured hierarchy, the Parent Element field, and, when that field is empty, Jira's native Parent.
Sandbox and sync
The sandbox (Draft) lets you move, stretch, or edit dates on the Gantt without writing to Jira until you click Sync.
Roll-ups and risks
Besides bars, Stratify shows aggregated effort, an optional date toggle, and Blocks dependencies with visual alerts.
