First, thanks for this important module and library!

Wouldn't it be nice, if we could insert more than the default 128 Characters in the Exclusion Fields?

Workaround:

/**
 * Implementation of hook_form_FORMID_alter()
 * 
*/
function mymodule_form_phpids_admin_settings_alter(&$form,$form_state) {
  $form['filters']['phpids_excl_fields']['#maxlength'] = 512; 
}

Also an new hook to add exceptions by module would be helpful, for example for Piwik-Module, which needs the exception "COOKIE._pk_ref.*" to work well.

Kind regards
