Can the width of a vertical or horizontal scrollbar change in at least Pivot and Straight tables?

When users are trying to move up or down on a vertical scrollbar or side-to-side on a horizontal scrollbar, it is difficult to grab the scrollbar to move around lots of data.  In addition, click right above and below the vertical scrollbar doesn't allow moving up or down as users are able to do so with the Qlik native Pivot and Straight tables.   Can the width of a vertical or horizontal scrollbar be configurable to increase the size for easier navigation around data?
