Hi
@PB170 as mentioned earlier, in the new I scale down the number of rectangles in the “trail” based on the number of windows on screen, starting with a maximum of 4 rectangles and dropping to 3 or fewer if more than 4 windows are being zoomed. I also now skip zooming windows that are mostly obscured or too small. The overall effect is cleaner. You will see this version soon. 4 rects looks better than 3 to me if the number of windows is sparse.
