I have many things but would like much better seo, I still think d7 is totally lacking. I would like a automatic sitemap creation and update when anything is posted, it writes the link to a sitemap. Page titles, keywords, descriptions, tags, etc should be able to customize much more for seo optimization. We need a moderation area with specific permissions available for the moderator. An admin can't do this alone on a busy site. Everyone needs time off, so much more moderation options is needed. Additonal see more documentation would be nice, and more detailed server requirements as well, the basics are only mentioned, there are alot of other php settings not mentioned that at the current release is required. Others could be recommended as preferrable. I know there is much more I would like to see without even considering d7, maybe I will add to this.
