This is just a simple request to update CLEditor to the latest version, which CRED uses for WYSIWYG Fields.
Right now it's running CLEditor version 1.3.0 which came out in 2010. The latest version (1.4.5) was released July 2014, and has a lot of bug fixes and improvements, including adding additional events like 'blurred' and 'focused' which provide very easy methods to interact with the field.

Would be great to get CLEditor up to date so it's not necessary to modify CRED's core files.
