Reports, and possibly other areas, but especially reports, are hard to navigate because you often have more columns wide than you can see, meaning you need to scroll left or right. Unfortunately a) unless you know there are columns you can’t see the lack of a scrollbar gives you no indication there is more and b) to have any hope of A not being a problem, you have to scroll to the bottom of the report first, which is not great.
Please have left and right scrolling available without the need to go to the bottom of a report (which can be quite long), then make your adjustment, then scroll back up to where you were.
