CKEditor 4.5 added HTML5 drag-and-drop file uploads. This can be done by using the uploadwidget.
We should support this feature in Drupal 8 core too and add it in a minor release by creating a custom plugin which handles drag-and-drop image uploads.
- Add uploadwidget
- Create the new plugin which should automatically open the image dialog when and image is dragged and dropped on the CKEditor textarea
- Usability testing
User interface changes
Data model changes
