Nobody has written in lately recommending any tools or programs or systems that have been improving their freelancing/editing/writing lives, but I did find this recommendation for Scrivener from Apple Matters:

If you are a writer, there's no shortage of applications to help the creative juices flow from mind to pen to paper - or should I say, to keyboard to screen. Be you a novelist, script writer, journalist and so on, there is an application for you to help your writing process. One I've taken a shine to lately is Scrivener.

Some of Scrivener's features that stand out are:
- Full screen editing. This is not a new invention by any means, but Scrivener has it and has a very good implementation of it. When I'm writing, as an article grows I need to see as much of it on the screen as possible, especially when I'm editing. Scrivener presents a totally clean screen but does show a scroll bar if you move your mouse to the right edge of the screen, and an information if you move to the bottom of the screen. The colors for the full screen are customizable - I've changed mine to black text on an off-white background.

More here on what Chris Howard likes so much about Scrivener. In the meantime, if you have a recommendation for other readers--whether it's a new software or filing system or ergonomic keyboard, don't keep it to yourself!
