Its a good script indeed, it work just fine as it is, but if you don't have the skills with Ruby to change the others customs scripts that you may have, this script will ruim a project. It fails to work with most custom scripts like Menus script. Whatever the custom script uses a window process, or it will fail or will causes horrible window misspositions.
The idea of this script work is good, but its unapplicable for most people.
