Documents?

Here's andrew (Our Supreme Lord and Overseer)'s official announcement for the new Documents feature, which should explain a bit.

Basically, many users wanted the ability to write their stories (and other things) on Notebook, rather than just worldbuilding, and having the Scratchpad was difficult to use for people like me who had filled it with lots and lots of different ideas (I had bits of poetry, unfinished critiques, notes on my magic system - it was a mess). The new feature allows us to put different notes in under different headings, and it also supports some nice formatting and autosaves as we write, which are both really handy!
