FYI: Plugin config keys now sit underneath the top-level 'config' key, instead of being at the top-level. Other non-plugin config keys remain at the top level.
Sample config tree:
- toolbar
- items - array of toolbar buttons
- plugins - array of enabled plugins (in form of filename.PluginClassName)
- config
- alignment
- htmlSupport
- heading
- image
- drupalImageUpload
- language
- table
- bodyClass
