Awesome plugin. Here are some suggested upgrades to the plugin.
- Tickbox for "Add nofollow to all external links"
- Ability to adjust nofollow on menus
- Add sitemap.xml function
- Add analytics code insertion (like the webmaster insertion you have)
I love your plugin so much, I promoted it in my blog - http://www.nustudio.com.au/wordpress-seo-ultimate/
I would also encourage anyone else with upgrade ideas to post them here. I'm sure the developers would like to know how to improve the (already fantastic) plugin. This is what the open source community is all about.
