Well, I found that I needed this, if only because I'm really weird about knowing certain things when I'm starting to plot stuff. And so, I made a list, and then ended up splitting it into a couple of lists. Hope it helps someone besides me ... and if I have a designation/whatever wrong, feel free to correct it.
