So, you're writing a thing.
Fantasy novel, historical timepiece, graphic novel script—no matter what it is, you're bound to have characters, plots, and settings swirling around in your head. But why on earth should they also be swirling around in your doc files?
Now, I'm no pioneer. Many writers will tell you that Google Docs doesn't quite cut it, especially if we're talking long-form fiction. That said, I'm certain that my replacement, Scrivener, beats the rest by ten leagues through the lands of Mordor. (No, really.)
First off, Scrivener's blank page is never a blank page. "Page 1" is not so much a page as it is an endless scroll, allowing you to chase your ideas without the disruption of page breaks. On the left of the screen, you have your modules—which can be shifted up and down to fit whatever hierarchy is most helpful—and, if you're a "plotter" like me, that's likely where you'll begin.
Each module contains a blank sheet—although some, like "Characters," come with a nifty little template—and can be dragged inside each other, as I've done with "1880-90s Clothing" and "Research." Such nested modules can be collapsed using the arrow to the left of the icon, creating a nice, tidy workspace with everything you need inside of the same "document."
In addition, Scrivener has several little icons through which you can personalize your modules. You can even personalize their contents by creating your own templates!
Freedom, concision—it's a bit of an oxymoron, huh? But it's true! Scrivener can hold the whole of your imagined world in a single, readymade document.
TL;DR - Scrivener makes Google Docs look like a post-it note.
