I really like minimal writing programs and I don't like to write in the tiny posts boxes. The best for me are ones that remove all the clutter and just leave you with a fullscreen of your words. So I am going to share these with the guild because I'm sure a lot of people don't know about their existence. If you prefer some other program with more organizational features for novelists and such, feel free to share them here.

[i]Linux only[/i]
I like PyRoom. It lacks some features but it is what it is, a barebones writing environment.

[i]Linux, Windows, OSX[/i]
FocusWriter is my absolute favorite. It features a robust theme customization. For example have a look at [url=http://blog.scrybr.com/category/focuswriter-themes]some themes[/url] this person developed. There is also a really neat feature with focus writer that relays typewriter sounds as you press down keys and press enter to make a new line. Also there is goal settings. So you can measure your performance. You can set a word limit that you want to hit, or just a time limit that you want to stay focused writing for.

[i]Windows[/i]
WriteMonkey is for windows only. And If I used windows I would use WriteMonkey. It is feature rich with a  large thesaurus, customizable themes, customizable typing sounds and progress tracking. There are also many community created plugins!

Well that's all for now, there are many others. I just wanted to introduce a few. I hppe you give them a try and see how they really help with your writing. Again if you prefer a more feature-rich novelist program with chapter, plot, character organization-features share your experiences and recommendations!
