This is a major update. For one, this plugin has been lying in the WordPress plugin repository since even before the repository existed in this form. So, I cleaned up the files and folders to conform them to the current use of the repository.
A quicktags button titled “OBW” has also been added which you can use in the HTML tab when composing a new post / page.
The code has also been fixed for better compatibility with later versions of WordPress.
