Add ability to add button on pages instead of just nodes

It would be nice to have the ability to add this on pages instead of just nodes. While your doing that it would nice to choose which selectors to add it to instead of excluding it.

My Scenario:

I have a blog content type that I want to add the pinterest hover. I also have a panels page that needs the pinterest hover but I only want it on certain elements. While I could add all the elements to exclude I feel like it would be a lot nice to just add the element we want to add it to (or both) instead of naming every eleement that we don't want it to.
