• Corkboard – In Scrivener, every document is attached to a virtual index card onto which you can jot a synopsis; moving the cards on Scrivener’s corkboard rearranges their associated text in your draft.
• Outliner – View and edit the synopses and meta-data of your documents in Scrivener’s powerful outliner. Organise your ideas using as many or few levels as you want and drag and drop to restructure your work.
• Scrivenings – Scrivener’s innovative “Scrivenings” mode allows you to move smoothly between editing your document one piece at a time or together as a whole.
• Statistics and Targets – A live word and character count of the current section is always in view at the bottom of the screen, and you can set a word or character count target for each section.
• Full-Screen – Because sometimes you want to blank out the rest of the world while you write – or at least the rest of the screen. One click in Scrivener’s toolbar and you can leave the rest of your desktop behind and write distraction free.

My only complaint about Scrivener is that there’s no GNU/Linux version.
