I would also add regarding the Google Calendar being just one direction.
Interestingly, if you unload your G calendar connection from the EN calendar widget the default message on the widget is: "Connect your calendar and link notes to events for easy access". Well, in my mind, the word "link" means there is a link between the note and the event and should the event be in a Google calendar then one would expect a proper link. Then it goes on to say "easy access". Questionable?
