Very useful for tracking a site if we have been to that site before.

Suggestion:
* Ability to save into a database. So you can preserve your old data after deleting browser history
* Combine /, ? into same data. For example: xxx.com/xxx/1234 is detected as another website from xxx.com/xxx/1234/ even though it's the same. Also xxx.com?si=xxxxx should be the same as xxx.com
