It's been a while since I used the plugin. I was under the impression that you could mask all links globally, and then unmask them on a page-by-page, link-by-link basis. I found an old blog posting to that effect.
Wasn't there a window underneath the text editor that listed all of the links on the page, and then you could click a check box for the links to unmask?
In any event, for siloing purposes, I want to mask the entire top nav, and only unmask the sidebar navigation links. How would I accomplish this?
