I just started working with "IT services" and it seems the ability to easily re-arrangethe tree structure is currently not available.
I would like to be able to drag ServiceB below ServiceA and TriggerB above TriggerC under Frontend => Configuration => IT Services.
Example:
root

• ServiceB
  • TriggerA
  • TriggerC
  • TriggerB
• ServiceA
  • TriggerA
  • TriggerC
  • TriggerB
