Dragging images inside of rich text editor
Just looked into this and it’s a Craft bug. If you add an image manually using the “Insert URL” option, the image can be dragged around, but not if you use the “Choose image” option, which opens Craft’s image selection modal.

Saving the entry and coming back to it (or just typing Command + S) will also make the image draggable, regardless of how you added it.

We’ll get this fixed.
