I've tweaked the default point sizes for the .ds graphic. I've also changed the opacity of the difference scores from 25% alpha to 50% alpha. Below is the result: before is on the left, after on the right:

I'm open to considering making those point sizes an argument, but I think that's too much to push through before our ggplot2 deadline. I'd rather get the package rock-solid and ready for release, then use our next version to focus on more visual improvements.
