Event name and variant

I understand what you are trying to do here but I don’t see how implementing this will help all the plugins users. You won’t be tracking variants for every page on your blog, do you? Most likely, you will be tracking variations on landing and sales pages.

So, just add the mixpanel.track script along with the variant event on those pages and it should work fine. But if you really want to track variations on a whole bunch of pages, just let me know here and I will send a separate zip file with the changes just for you.
