Always thought it could be interesting when spectating to see which click was used. The most appropriate way would be to have a skin that shows it.
You could even extend it to distinguish keyboard/mouse/tablet "clicks", although just left/right is already enough to see whether a player alternates, singletaps or combines different techniques.
