Congratulations to the team for rolling this out it's wonderful! I'd Love to see the arrows that allow for selecting another date also include a calendar icon to pop open a calendar moving the arrows to the top right and left corner of the calendar to switch months.

I also am hopeful that if and when iOS rolls out interactive widgets a large widget like this (and a full suite of widget offerings for that matter) will be implemented. (It would live on my home page of my phone!)
