Dragging onto button != dragging onto window
Submitted by Calum Benson
Link to original bug (#109677)
Description
Dragging an icon/link/whatever onto a window list button should be the same as dragging it into the application window. E.g. if I have GIMP running but minimized, I should be able to drag a PNG file from my desktop onto the window list button and have GIMP raise itself and open the file. Or I should be able drag a link from an open email in Evolution to a broswer button, to open the link in an already-running, presumably non-default browser.
