Frankly, I'm getting the feeling that StandardListItem exists only for the purpose of simplifying sample apps. Its basically unconfigurable, and they don't appear to have added anything to it with each Cascades API update.
What I do wish RIM would do, however, is publish the source code to a custom UI component that behaves exactly like StandardListItem. With such a sample, we could extend it however we want, yet still retain all of its intended behavior. (such as highlight-on-touch, etc.)
