Scrivener!

I've been using Scrivener for a few weeks now, and it's a huuuuge improvement over Word and my old system of files. There are a few features I miss, like being able to see the non-printing characters (I know, I'm weird), but it doesn't annoy me the way Word does, and has so many nifty features. For one thing, Scrivener's organization way beats mine.

so in case you didn't get it, I'm really, really happy with this program ^^. And I'm really, really itching to have time to use it for fic writing.
