WriteRoom/Darkroom/?

[dicesquirrel]

Hello everyone, long time listener, first time poster.

My problem is this: I was reading Lifehacker.com, and they suggested a Windows app called "Darkroom," a clone of the OS X program "WriteRoom."

Basically, I really really want this simple functionality, and I haven't been able to find it via any text editor for Linux. Does anyone have some suggestions? I need these features:
- Fullscreen, no window border
- Green text, Courier New, 12 pt
- Ability to pad the text on either side, creating a column like WriteRoom does, for ease of reading, while not interfering terribly with the formatting.
- Easily save to .txt, preferably with a nice key combination like ctrl-s
- No title line or formatting lines like nano/pico
- Not totally necessary, but it would really help: word-wrap!

I've tried out vim, found it way too complex and byzantine for my simple purposes. I tried using Abiword with a black background, green text, in F11 fullscreen mode, but that retained a menu bar and window border. I suppose if I could get rid of the menu bar I could live with the menu bar.

Thanks for your time.
