unfortunately tracker control cant be on while rethink is on or vice versa. I have also noticed that you shouldnt trust the system to block anything. Even if you forbid datausage for something, its not trruly blocked. Also google cant be blocked by system at all, but rethink can do that too, though then you need to manage the settings every time you want to use google's services but it doesnt seem to cause any awful problems in general. That program is one of the best things i have found for a while.
