I would like to be able to provide an external categories file that the script would process in addition to the history files that are fed to it. As each activity record is generated the script would check the categories file to see if that site name is categorized and then add the appropriate category to the activity record.
Then I would like for the tool to be able to show only certain categories or show everything except some categories. This is a great feature for forensic examination of browser history because it would allow the examiner to exclude any activity records that are work related or records that are not suspicious and do not warrant further examination.
