yWriter5 is FREE and much better than newnovelist and dramatica pro. It's a really nice interface with drag & drop features, character outlines (bio, pictures), locations, descriptions, notes, etc. You can actually drag Ch.22 up and drop it between Ch. 5-7 and then print the whole thing out. All the information is stored in .txt files, so it's easy to export a full manuscript, open it in MS word (or other word processor), and apply manuscript formatting.
If you're bored with a scene in Ch.9, you can jump to Ch.22 and work on a scene you've been looking forward to. I open all my new projects with 30 empty chapters and assign 3 scenes to each chapter (90 scenes). This makes outlining so much easier to manage. If you end up doing more or less, you can easily create or delete chapters and scenes.
It has a built in dictionary/thesaurus/spellchecker and button to read the text out loud so you can hear your passages and notice flow, pace, and rhythm. There's wordcount and autosave options.
The chapter descriptions can be printed out as a single document for an easy synopsis draft. yWriter can update on it's own too.
It comes with a new project wizard that walks you through the simple steps to create your project and a quick start e-book guide on how to use the program and all the cool features.
The free download is here.

It's good to backup often and even keep a weekly backup on a thumbdrive just in case something happens to your computer or if you want to go from using your desktop to a laptop. This program works from a usb thumbdrive.
