Hello,
I'm currently using RS SEO on my Joomla sites. I've recently used a plugin on my wordpress sites that has a live "checker", tips and counter next to the meta information. This is similar to How rsSEO works, except within each item/article, as you are creating it. It helps to guide the publisher as they are creating the content, rather than after the fact, in a separate component.

I'm not sure if this would ever be possible with rsSEO currently, but rsSEO seems to have all of the same hints and "grades", it would just be nice if those tools were available while creating the original content.

I've also stumbled upon a similar tool in the JED that accomplishes this task, while being minimally intrusive, it was called "Article Seo Checklist". Although, it doesn't seem to be in active development.
