Thanks, this is a big improvement.

I like the default modifier actions - they match how drag and drop works
on my other apps. I was worried having the modifiers independent of the
Emacs modifiers might be a bit confusing with non-default bindings, but
in practice it doesn't cause me any trouble.

I also tried as many different dnd operations as I could think of. They
all worked as expected except one - when I try to open a malformed URL
Emacs creates a spurious buffer and freezes momentarily (C-g to clear).
Specifically, I selected the text "file://~/test.txt" in TextEdit.app
and dropped it into Emacs with Alt/Opt held down. Properly formed URLs
work as expected and open the file.

Thanks again for working on this.
