When I receive FindTime requests
As a sender and receiver of FindTime requests you already have full access to my calendar. As a receiver, I have to have the browser page showing the invite times along with my calendar up to know which times I should vote for. Instead of side by side, show my calendar next to the time options or even better, show me automagically which times in the invite work for me and which times don't.
This type of information on one screen would make my response times faster and more accurate.
