My wish is that Needles would make the Transaction Details screen smaller.

Where you click on the green plus sign to open transaction details on the value tab, the screen takes up a large part of the screen. You cannot see the numbers behind you. Most of the time I am making an adjustment and I need the number behind the screen. The transaction detail screen is way too big. I use about 10% of the screen. You can actually make the screen the size of your monitor!
