Photoshop allows to drag-n-drop artwork between documents in same place, when you hold Shift.
In Illustrator, no matter what you hold, artwork would be dropped where cursor is pointed, with no respect to original X,Y coordinates.
I desperately need this!

Quite often I have to copy artwork, containing huge raster images, from one document to another. I need them to be placed in same place, snapped on grid, but AI just drops it. The only way to keep coordinates — is to copy/paste in front/place, which takes an EON to do with my big raster images.
