This plugin was a snap to use. I like the fact that it enables different sort orders. If it weren't advertised as Simple, I would ask for a few options, like the option to display Posts or Pages or both, and the option to disable the public-side sort drop-down. But they're not critical.
What kept it from getting 5 stars is the CSS that sets the font size of the list items to 15px and the line height to 1.6em. These values should not be set by the plugin; they should default to the site's list styles. Having the classes in the HTML so that someone can style them differently from other lists is sufficient.
Note Feb 22: See my comment. I updated the rating from 4 stars to 5 stars.
