Downloader: Gmail drag-and-drop now works in Safari, too

The Gmail team continues to push HTML5 hard, and their latest efforts mean that Safari users can now drag and drop attachments onto their Gmail window (just like Chrome and Firefox users have been able to do for a while).

The same goes for dragging images into messages. One feature that Safari users now have over Firefox users is that "new windows outlive the original Gmail window." This means that you can pop out a chat window and close the original Gmail tab, and things will keep humming along just fine. I hope that the final version of Firefox 4 will support this.
