> - airhorn and/or light saber sound effects,

I will take the light saber sounds.

With stereo-spacial transformation, so the sounds "direction" and "distance" match my own physical dynamic orientation relative to the cursor's motion on the screen.

And, the ability to open a small window, which gives me the cursor's visual point-of-view, as it zooms through the graphics on the screen.

Also, each traversed character should get "hot" as the curser goes over it, indicated with a stable glow for a quarter of a second, followed by an exponential fade over another second.

I think we can all agree that when in flow, functional distractions need to work harder, be more immersive, to be effective.
