I know this is old now but I love this addon, I managed to add it to /admin/includes/boxes/reports.php after reading tuts on the forums, unfortunately it broke my admin menu in the new oscommerce and left me stuck for a while. Easy fix just edit /admin/supertracker.php.

Add near the top around line 34:
require(DIR_WS_INCLUDES . 'template_top.php');
This restores the nice admin menu .

Remove from line 88:


or you will end up with 2 left side menus
