Hm, I think it’s currently highly confusing (some would even say misleading) that the Mac App Store app is just the Safari extension. I think it’s worth pointing that out in the app description as currently people think it would be a OS-scope blocker.
Maybe this is what you want to describe in the second paragraph of the app description. However, I understand it as "we brought the iOS Content blocker to the Mac" which for me means, the Mac app is a operating system wide blocker ("Firewall").
Now I don’t think I need to explain why this makes a huge difference, so I hope you’ll make clearer what the app can do (protecting your privacy in Safari) and what it doesn’t (protecting your privacy in any other place other than Safari).
Thanks for considering the feedback. I love the app and use it daily on the smartphone and would love to use it on the Mac as well but since I don’t use Safari, the current app is useless to me now.
