The names of the parent tasks don't seem to show up anywhere in planner. Not in priorities, not in backlog, not on the calendar view itself, not on the 'focus time' block in the calendar view. Just nowhere.

I frequently have similar (or identical) subtasks for multiple different tasks. i.e. I have 5 different things (so 5 tasks) that each need to move through 6 different stages, so each task has the same 6 subtasks. Without being able to see the names of the parent tasks in the planner, it gets wildly confusing.
