I enjoy the concept of a roadmap, a visual Epic view (we use Big Gantt for this today but often it's overkill).
The issue:
- Add start & due dates for an Epic
- Add a child task and add a due date which is longer than the Epic's due date
Result - roadmap is not updated.
Ideally the roadmap would show this extension, perhaps in a different color denoting that something is now stretching out after the intended due date.
