Just wanna say that I'm loving this feature! very easy to place notes, looks and works great.
as others have said a Printing/PDF feature would make this the Best thing ever.
Edit: the scrolling is a bit odd. would it be better for simple scroll to move up/down, and ctrl+scroll to scale it instead?
Works great here!
