There are times where I would like to be able to scroll from day to day without taking several click to open the date picker and select the next day. For example, in the Unisearch tool you might want to scroll through a few days before and after the current day to see how the selections change or after a quicktest, you might want to scroll through day to day and see how the stocks peformed. It is quite cumbersome to do that now, and adding arrows to scroll to the previous and next days would be much less time consuming.
