I've only been playing with my Reader for a couple of days, and I'm new to the forums, so forgive me if this is asked-and-answered somewhere else..

On other devices my preference has generally been to invert the screen, reading white text on black background. This usually makes it easier to read ebooks on an LCD screen for me. Obviously the Reader's screen is completely different and it's very comfortable to read as it is, but I'm wondering if it wouldn't be nicer with an inverted screen. In particular I'm thinking that it might make page-turning a little less jarring because it would only flash the text not the entire page.

Anyone know if it's possible to invert the text, either on the device or by pre-formatting the documents in some way? Is there a hack of some sort?
