It's useful to be able to mark tasks as important, however I have a lot of tasks that are unimportant that I would like to be prioritized at the bottom of my list.
The Prioritize mode still seems to mix in some "medium" priority tasks with very unimportant tasks, and I'd like to be able to guide the system to know which tasks are things that can wait a long time.
Even if I try putting something as "due in 6 months" it still remains in the middle of my Prioritized list.
