Under Mac OS 9, users had the option to restore any “Trash”ed files (before the Trash is emptied) back to their original locations with a simple “Put Away” command. For some reason, this capability was lost in the transition to Mac OS X. In the latest Snow Leopard builds, it’s back (as “Put Back”). So any accidental disposals can now easily be restored with a simple click. Again, this only works for files that have been moved to the Trash but not yet “emptied” (deleted).
That would rock my world.
