I would love some sort of internal linking feature with this plugin.
For example, a section in the post edit screen where I can quickly add internal links to this post from a preset number of keyword/URL combinations that were set up previously.
So if I want keywords X and Y to point to URL Z, I can highlight those keywords in my post, and click a button down below for those keywords, and it will add the link.
An auto linking feature might be good as well, where I tell which keywords I want to focus on, and it goes back and adds URLs to previous posts, or automatically links keywords as I publish posts.
There are numerous plugins that try to do this, but they are mostly all broken.
