Gmail Labs' new Offline Gmail feature now allows users to specify a maximum attachment size that should be downloaded for offline access. Your options range from 10KB to 5MB in size. Alternately, you can choose not to download any attachments if you want to save on disk space or all attachments if you've got plenty of space. (Keep in mind that the maximum attachment size in Gmail is currently 20MB.) We're not seeing the 0.2 options in our Gmail accounts yet, which means this is likely one of Google's slow rollouts. Still, Google Operating System suggests that disabling offline access and then re-enabling it may do the trick, so if you're really eager, you might want to give it a try.
