We have enabled categories on pages and have posts and pages that share the same category. The side effect that we are getting both posts and pages are showing on the news sitemap and that is not ideal. I can see on line 183 of the plugin you are calling out both pages and posts directly. Is it possible if you could add in a switch to allow us to manually select what post types are included and potentially even support custom post types?
Custom post types would be a bonus but being able to select post, or pages, or both would be amazing.
