In Windows 10, if the taskbar is vertical, there is a large amount of padding above, and below the clock:
When the "Show desktop" button is hidden, this becomes even more noticeable, since the clock sits above the bottom of the screen by quite a large amount.
An option to remove, or reduce this padding would be nice.
