A Notes property page was add so that you can annotate the issues, reminders, or other types of notes associated with an object. A Note can be entered using formatted text - with options for Font, Color, Style, Size, Bullets, Alignment, etc...
The Notes property page
When an object has a Note, an asterisk (*) appears after its name in the Explorers. An option to toggle the display of this reminder was added to the Model Explorer context menu (though it applies to all Explorers) and in the Tools/Options/Model Explorer dialog.
