kPasteboardTypeFileURLPromise source example

Question

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)

Answer 1

Acorn's layer list provide kPasteboardTypeFileURLPromise. You can drag the image thumbnail out of it, and it'll do the right thing.
