It would be hugely helpful if the option to hide notes (and comments!) was sticky with the document as a preference. I most frequently use my drawings without notes and comments. When I open the drawing I find I have to hide the comment and note bubbles every single time. This is irritating.
Alternatively, if there was a faster way to do this without fumbling through two check boxes in a menu or if these settings could be attached as an action on a clickable object in a drawing this would be an improvement.
