Calendar: needs an adaptive design
Basically, the Calendar is not adaptive and there's a lot to think about regarding how its layout will adapt to form-factor and window size changes. I think the Month and Week views will be relatively scalable but addressing the navigation on mobile/small windows will be a challenge.
