the page Users Permissions can be *verry* long.  Borring click so much checkboxes
 
 
I suggest add a nice Global Checkbox in each role header, and using jQuery should be that simple:
 
$(function() {
  $('#check_all_role1').Click(function() {
    $('.check_role1').val(this.value);
  }
}
 
How can I help with that, to add in Drupal 6 final release?
 
Its time yet?
 
What PHP file, in core, should I change it? any hook?
 
 
Sorry for so much noob questions, this is probably documented in Drupal.org, but I didnt find.
