KeyNote, when it comes to keeping notes, is my baby. It's shareware that keeps me alive -- you can do trees and whatnots in it, so I have my originals sorted by (and this is just one tiny section):

Seriously, when I want to find stuff? I damn well be able to find information. I should actually have more notes on here than I do; some of them are in various wordfiles and need to be backed up on KeyNote so I can find them. (BTW: my original stuff all takes place in the same universe, so I really do need to keep track of my stuff really well.)

Zeke and Devin are fun.
