One of the reasons for a 4 star rating on most all the ad blockers and popup blockers I give is because a number of popups might be presented as blocked but there's no information on what popups are blocked: i.e. the url of the blocked popup. Ad-Block and many others simply do not provide the offending url. I understand there is a great deal of overhead with keeping a log of what was blocked. A simple way of turning on and off the logging process could be added to make the experience better. A feature in the advanced options to make the class active and an extra button on the pull down window to start and stop the log would get 5 stars from me. You'd have something no one else offers.
