Take this for what its worth.
I will be deleting Scrivener from my computer. It is to anal for me to handle. After attempting to use it for well over a week now, I am still lost.
The program is basically multiple files being drafted for a specific project. It allows you to keep track of characters, places, and scenes in small chunks. Supposedly you can jump back and forth with greatest of ease.
I get lost in the transitions.
The same thing can be done with three Word files open at the same time and stored in the same project folder. I have a 17" screen which makes this very comfortable.
Scrivener also has too small a working screen for my tired old eyes.
Last word -- I can see where a more organized individual might be able to use this program to some advantage. For me, it just doesn't work.
However, with whatever, get writing.
