Mine is a personal tip regarding extending libraries/etc:

Where possible, use the original library methods but wrap them in code or replace the code using a condition to extend the functionality rather than duplicating and changing the original. Makes it quite a bit easier to upgrade if the original function changes.

MY_Lib.php

Code:

<?php
class MY_Lib extends CI_Lib
{
  function MY_Lib
  {
    //Standard Initialization
    parent::CI_Lib();
  }

  function _extended_function()
  {
    if(condition)
    {
      //my version of code
      return;
    }

    parent::_extended_function();
    return;
  }
}
?>

I find that I can accomplish most tasks using this method with very little copied code and it is easier to update should the base function change (since I don't have to figure out what I changed).

Not an end-all be-all but more of a preference for keeping things clean and updateable.
