Drag and drop

Every place in the app where dragging something does something useful.

Dragging works in most of the places you would expect it to. The full list:

Drag this	Onto this	And you get
Image files from Finder or Explorer	The Library	The files are uploaded into your library as your own assets.
Image files from Finder or Explorer	A prompt’s reference area	They are attached to that prompt as reference images.
Image files from Finder or Explorer	The scene canvas	Each file is uploaded to your library and added to the scene as a centred image layer.
An image in the Library	A prompt	That image becomes a reference for the next generation.
A layer on the scene canvas	Anywhere on the canvas	The layer moves, with guides snapping it to the canvas and to nearby layers.
A row in the layer list	Another spot in the list	The layer reorders; drop it on the middle of a group row to move it inside the group.
A row in the layer list	A folder or the desktop outside the window	The layer lands there as a PNG file named after it.
A step’s output in a flow	Another step’s input	The two steps are connected, passing the image along the chain.
A flow input or step output	The flow’s outputs	That value is published as an output of the whole flow.

Drop zones highlight while you drag over them, so if nothing lights up, the target does not accept what you are holding.
