At the moment when you enable A2A on blog posts, it appears on all of them. There are some posts where I wouldn't want it to appear.
My recommendation would be to change the setting to: Enable Add-to-any on blog posts by default (OFF/ON)
And then this populates a setting added to the Blog post/edit page accordingly. This way A2A can be added/removed from individual posts or pages.
Unless I'm missing something and there's an easier way of doing this?
