#UNDO!
This sounds like a great option. But I've gotta say that I would never
use it. Using "automatic saving" functions in the past would blow my
mind when I'd go to do an operation and be forced to wait while the
file was saved to the hard disk (I'm _so_ impatient sometimes!<g>).
It's just personal taste, really. I guess I just like to control
(exactly) what and when I save. On the other hand, I know of many who
were saved by this very feature and they swear by it. So like I say,
it would be a great option, especially if you can somewhat control
how and when the saving is going on.
