Because of wcag-related issues, we regularly need to modify the way the ck-editor is used. In the Text/HTML modules the portal settings for the editor are used. We use this in combination with an extra config file.
Even though you can choose the three types of editor settings (simple, standard, full) in Form Builder in the OpenContent module, I still need to configure these paths manually in options.json. I hope there will be an easier way to do this in the future... The current way is very vulnerable to be overwritten by an administrator that is not always aware of his or her actions...
