Which application of Apple does support dragging of kPasteboardTypeFileURLPromise items?
I am implementation a kPasteboardTypeFileURLPromise dragging destination and I would like to test it against a dragging source that can be trusted.
(Finder is an example for dragging destination, but I'm looking for a dragging source)
Acorn's layer list provide kPasteboardTypeFileURLPromise. You can drag the image thumbnail out of it, and it'll do the right thing.
