If you're using Structure app to view and manage Xray related entities right from a "structure", the enhanced Xray extender now provides the ability to:
see and manage associations between Test Plans and Test Executions
choose to synchronize Tests to Test Plans whenever adding/removing Tests from the related Test Executions (e.g. if you add a Test to Test Execution, it can automatically be added to the related Test Plan(s))
choose whether to manage or not Tests directly under Test Plans
