This is a very simple change, but sometimes it is the simple things that count.
If you go to one of the screens which has a date range filter at the top, like the cashbook screen for example, previously you had to select an item from the filter dropdown list, and then press the Load button. Having to press the load button just seemed a bit un-necessary. So now you dont have to. As soon as you select an item from the filter list, it will automatically perform the load for you.
