You can start a project at any time, you get a 30 day calendar, just write more than 1667 words a day, and you'll have a 50,000 word novel.
Word count at the top of the page all the time. Word processor theme by default. Each day is a new editor window, so you just focus on what you need to do today.
Want to see the novel in full? There is a fully readable, all in one, page. Also you can download the raw text at any point to keep as a backup, or move to a different editor.
