Everyday as designers you are faced with trying to recall and remember all the reasons why your designs went from one iteration to another.

This command has been in Inventor forever, but often overlooked, or maybe I am just a fan :). Either way check out this video for a short example of using CAD sticky notes with Engineering Notebook.
