I currently have my DisplayFusion taskbar on the right hand side of my second monitor, and the Windows taskbar on the left hand side of my primary monitor. On the Windows taskbar, when I hover over a window grouping, the window previews are shown in a vertical fashion. However, on the DisplayFusion taskbar, the window previews are shown in a horizontal fashion. It would be great if the DisplayFusion previews were shown vertically, to match the behavior of the Windows taskbar.
