Pack Station scan to verify screen adjustment

On the item verification screen, please make it possible to adjust how much of the window is used for the items on the left vs how much space is used for the packing fields on the the right? Like making a spreadsheet cell bigger/smaller.

My screen is horizontal. It leaves a lot of unneeded space between the product name and the quantity counter, but there isn't much vertical visibility to edit the package details without a lot of scrolling.

Ideally, I'd like to be able to drag the scroll bar for the items further to the left to create more space for the package details on the right.

Another option could be to make the black box with the print button low and wide across the bottom rather than a big block on the right.
