Some events might have descriptions, maybe room number or items you have to bring to an appointment or whatever. I would like to be able to see the description just like how you can see the location on the event itself (if there is room). It would be really helpful on the widget so I can quick glance that my appointment starts at this time, is in this location and to bring x paperwork.

Or the reason I'm writing this now: I have a medical test that requires a limited diet for several days before the test, I'd like to be able to glance at my widget to see when the diet is and what I can't eat.
