[Plugin: WordPress HTTPS] Sitemap shows http://

Hi, I’m using XML Sitemap Generator for WordPress 3.2.4 for the automatic creation of sitemaps for web crawlers. I noticed that google webmaster tools gives me a warning because the sitemap contains some urls with http:// to pages where I actually enforce redirection to https://.
So, this would be a nice future enhancement to make the sitemap generator aware of the https://. Thanks!
