I have a feature suggestion for Deeplink Juggernaut.
In the Deeplink Juggernaut > Add a new Link > Destination Type > Content Items:
4. Links (new feature)
You may already guess that the new feature is a Link added with the Links Manager of WordPress core (Blogroll) - where users usually store all external links
Just like the case of the other options... if the user selects “Links", the dropdown will appear and lets the user select a Link by title... And Deeplink Juggernaut will automatically change the autolinks href attributes if the Links are changed in the Links Manager!
I've been studing a lot of autolink plugins - maybe all :) and the only one that has a similar feature is call it LinkIt, but this one is very new and in development and a lot of his features simple don't work.
