Thanks to you. In the first place I was looking for an easy solution like this and tested lots of useless plugins. I was rushed and dind’t noticed the help link, so I had to figure out things, and realize how it works. I found the link to the help page once I have everything working :). The only more complex thing to accomplish was to realize that for code to be inserted in all the frontend, I just needed to select those sections in the Auxiliary tab. Maybe the wording “Auxiliary” didn’t mean like a section I MUST check out. Maybe the wording or the position in the UI.
All in all, I can say it is a very powerful and beautiful plugin, but its truly capabilities and power are not that intuitive or easy to be discovered.
Thanks!
