I asked on another topic if anyone knew about how to add the product review URLs to the XML sitemap.
I believe this is better suited as an actual feature suggestion than me just whining about it..
Please add an option for admins to specify whether or not they want their product review URLs included in the XML sitemap. Product reviews really give your site a boost in Google's eyes these days, and because the product review page includes a link to the product, it's got potential to bring traffic in and result in conversions.
