I was looking at a 360 panorama image and scrolling with my mouse's scroll wheel, and thought it would be cool if KView had options where you could ask it to wrap the image around at the left/right and/or top/bottom, so you could seamlessly scroll around in it.  I imagine it would be hard to do with a normal scrollbar (clicking and dragging it) without making the mouse pointer itself warp... but using arrow keys or mouse scroll wheel, it wouldn't seem very unnatural, just an infinitely wide and/or tall image. :^)
