Hate to be anal but I just reformatted my MBA with a fresh OS X Lion.

Has anyone ever, while working fast, saw the puff and sound of an item dragged from the dock and not know which item just got accidentally removed?

Nope. But if you can't notice which one it was chances are it shouldn't be there in the first place.

Not really... I am the same way on my MBA, iPhone and iPad... Its not being Anal its having things in a orderly fashion the way they originally were.

Yes, really.

Unfortunately, the Finder's Undo menu choice doesn't let you reverse that action. Apple should have made that work.
