Tasks within tasks

[caifalex]

Does anybody know if there is a third party application that will allow for better task organization, that is a program similar to the one included on the vogue (the clipboard with the checkmarks) but that you can actually rank tasks in order (not just high, mid, low) and that allows for subtasks. For example, say one the tasks is Grocery shopping, and within that tasks I have apples, oranges, and bananas... and that once I check apples, oranges and bananas the grocery shopping checkbox gets checked automatically (This isn't what I'll be using it for, but it's the same principle, it'd be for school related stuff now that I'm starting grad school I'll need better time management skills!)
