Lets say I need to build a fence on the weekend. That's the main task.
Sub tasks would be:
1) Find the best deal on wood
2) Find the best deal on paint
3) Find the best deal on concrete
4) Place order/pickup wood
5) Place order/pickup paint
6) Place order/pickup concrete
7) Saturday morning - lay foundation and fence posts.
8) Sunday - finish fence.
9) Next Saturday - paint fence.

It would be really nice if I could create the tasks 1 to 9 in any order and make them sub tasks of the main task. Therefore, when I complete task 1, the main task get marked 10% complete.
