+" Ensure the window has maximized height
+"
+" This helps restoring the window size after reopening sessions after
+" switching monitors (like from laptop screen to external HDMI monitor).
+"
+" We just want to quickly maximize the window and then restore it to
+" it's original size, to ensure all windows are refreshed.
+"
+" Maybe this is not a NERDTree workaround itself, but more like a
+" session workaround.
