Events on subscribed calendars (i.e. Facebook) can have long event notes. I don't need to see them in the popup. It makes scrolling through a day's events a VERY tedious task, especially if there is more than one Facebook event.

Apple iOS Calendar and others are smarter about this. You only see the notes when you click on the event.

PLEASE fix this. I've sent email to support a long time ago. It is not a trivial matter.
