How is issue hierarchy provided by Structure plug-in different from the standard sub-tasks?
Sub-tasks have several major limitations:
- sub-tasks are only a one-level hierarchy;
- sub-tasks are separate issue types;
- sub-tasks always inherit project and security level from their parent task.
None of these limitations are present in Structure. At the same time, Structure plugin provides all the features that sub-tasks have, and more.
