To ease the maintenance of sites I would make possible to have the third party scripts (generally speaking, this should, to me, applies to every modules) outside of the module directories.

For example

  • sites
    • example.com
      • files
      • settings.php
      • themes
    • all
      • modules
        • getid3
        • tinytinymce
        • views
        • ...
      • thirdparty
        • getid3
        • tinymce
        • ...

For Tiny Tiny MCE I just had to made a small modification to the tinytinymce.module file

  1. Adding:
    	$form['tinytinymce_scripts_path'] = array(
      '#type' => 'textfield',
      '#default_value' => variable_get('tinytinymce_scripts_path', drupal_get_path('module', 'tinytinymce') .'/tinymce/jscripts/tiny_mce/tiny_mce.js'),
      '#title' => t('Location of tiny_mce.js'),
    );

    in tinytinymce_admin()

  2. Changing:
             $path = drupal_get_path('module', 'tinytinymce');
         drupal_add_js($path.'/tinymce/jscripts/tiny_mce/tiny_mce.js', 'module', 'header', false, true, false);

    to 

             /*
         $path = drupal_get_path('module', 'tinytinymce');
         drupal_add_js($path.'/tinymce/jscripts/tiny_mce/tiny_mce.js', 'module', 'header', false, true, false);
         */
         $path =variable_get('tinytinymce_scripts_path', drupal_get_path('module', 'tinytinymce') .'/tinymce/jscripts/tiny_mce/tiny_mce.js');
         drupal_add_js($path, 'module', 'header', false, true, false);

    in tinytinymce_theme_textarea()

Of course some "help / instructions" have to be changed too.
An other advantage of this is to be able to easly switch between 2 versions of TinyMCE...
Do you like it?
