By default Diem brings you a flavored Markdown editor. But sometimes, the customer wants a WYSIWYG...
So this plugin integrates the best open source editor: CkEditor.
Currently only admin forms can receive ckEditors. Later, this plugin will be updated with a front ckEditorWidget.
The plugin is fully extensible. Only works with Diem 5.0 installed.
