The goal is to implement a drag&drop newsletter wysiwyg eidtor ([url removed, login to view]) in a php application that uses actualy CKEditor.
It should be possible to insert columns for presenting products within the editor (there is a plugin for the above editor avaliable).
A tutorial how to change the editor in the available php application is also available. (the tutorial is based on how to implement CKEditor)
A documentation which files has been changed (to be able to update the application without breaking the new editor) is needed.
