I really wish they'd get rid of that persistent Scroll banner on every page where the service is active. I'm not going to pay for a service to get rid of ads just to see a different ad.
And no, the ability to share to social media isn't a "useful" service.
I realize they need a way to remind users that Scroll is active, but there needs to be a much less intrusive way to do it, or else they're defeating the purpose of the product.
