When working with subtasks, the name of the parent task does not appear in the timesheet. It would be helpful to have it either in the task name (e.g. subtask [parent task]) or in the Location (e.g. Space/List/Parent task). Alternatively, group the subtasks by task and always display the parent task even if no time was reported in the parent task.
Task 1
> Subtask 1
> ...
Task 2
> Subtask 2
