I don't think Beamer would be counted as analytics. What cookies do they required? The implementation is a bit confusing for me to follow so I'd love to discuss it with you tomorrow. Looking cool though!

Looks good. I am still not 100% sure on categorising Beamer as analytical.

Nice solution with the new cookie category!
