customers have complained about the calendar/date picker being complicated to use. For example, if you want to see only last December's data, you need to go to the year, the month, choose a date and then it automatically brings you to the current date as the end date, so again, you need to go back and find December last year again and then choose the end date. In my opinion, it should just stay where you chose as the start date and then you should be free to choose the end date from there as starting point. if you make a mistake, and get out of the calendar view, you cannot cancel the selection it just keeps you there with no way to reset it.
