[swadexi]

Hi,,i'm new in developing prestashop,now,  my project is creating template for sale. in my template, i need new hooks. my qustions , is it allowed a module that creating new hook? because in creating a new hook, it will change/overwrite frontcontroller.php.. certainly, i will backup that file first on overide folder before overwrite it.and restore that file when my new customhook module is uninstalled. because it is for sale.,i'm affraid i will break the rule of developing new prestashop..thanks
