I down loaded the Kindle for PC last week. I remember reading in its "Future Improvements" screen that the current version does not have highlight and notations but it is something they might add. Then a couple of days later, there it was. Marvelous! Has anyone tried Kindles Beta "Note Sharing" site yet? Or maybe they call it "Daily Refresh" I think the name is still morphing. It is pretty neat:
