In general is OK but things could be improved as for example; why the hell if I stop visiting a web—or I just do it sometimes—it does appear before others that I do visit a lot as in "daily basis". That is why I do not give the five but the rest is pretty awesome. A simple ad-don for a simple thing. You can customize everything and from a couple of month you can even make a backup copy of your settings. I will be using this forever.
