I could not identify to group history "by date", as it's claimed, it just let's you distinguish between "today", "yesterday", "last 7 days", and "last 30 days", so almost no added value here over the built-in functionality. plus points for grouping by site though! much appreciated. but still there're some concerns about the actual correctness of data displayed - I have no stackoverflow.com in the "last 7 days" folder although I am *definitely* visiting that site every day!
