This is a great little tool for making lists and outlines. I used it for a while for my GTD project lists and I'm going back to it now, because it really helped keep all my little lists organized and updated.
It's also great for organizing written reports, and probably papers too for you college students.
It's not a free product but it's inexpensive and there is a free trial so check it out. (in your free time, not NOW lol)
