Currently task hierarchy is not preserved in the Tasks view, that is tasks are not visually indented under their parent task.
I think this would make a good voting item to see whether other people would like to have subtask hierarchy present in Tasks view. One drawback I personally see is that it would defeat the purpose of the auto-sorted list of todos to have to bundle subtasks together.
On a related note, maybe there can be useful discussion about how Amplenote could make task score work across task hierarchies such that the Tasks view utility is preserved.
