Please allow for subtasks (the triangle) to be shown all the time whenever there are subtasks (ideally to be able to dropdown infinitely), across individual project (I realize it no longer shows when I sort my tasks by due dates…) and also in ‘My tasks’. This will make things much easier rather than having to click into each individual subtasks all the way at the right!
There’s actually already a post for this request, suggest you add your vote there:
Subtasks in the list view are coming in the next few months in an updated My Tasks view. (Although I think it will be only one level, like projects.)
