WYSIWYG

I have solved the issue. It was hard to find but easy to add the solution to any theme following these steps:

• Get the 2 .js files (editor_plugin_src.js and editor_plugin.js) from
  http://www.tinymce.com/forum/viewtopic.php?id=16533
• Save them in a folder called “trailing”
• Upload your folder “trailing” to “wp-includes/js/tinymce/plugins”
• Add the following code to your functions.php

  function add_wysiwy_trailing_plugin($initArray)
  {
      $initArray['plugins'] .= ',trailing';
      return $initArray;
  }
  add_filter('tiny_mce_before_init', 'add_wysiwy_trailing_plugin');

Now you’re set. If you insert your element (image or table) you’ll have added spacing before and after te end of document.

Don’t worry the extra spacing will be removed if you save your post 🙂

I can imagine this would be useful for others too. I haven’t figured out yet how to write a wordpress plugin so i need to perform this manually for all my sites. I’d like to see this in default wordpress distro.

Like most of us know WordPress will indeed overwrite altered code (hacks). This is not the case here. Note that this plugin lives in a new folder which is not there by default. WordPress doesn’t delete added folders and files. During updates it replaces only your hacks of files it ships with.

The plugin gets added to the configuration by a hook. This is done inside the functions.php of your theme. This is not hardcoded into any existing TinyMCE or WordPress files.
