I've also wondered the same thing, battery killer or not it would still be a nice option to have..Wether it be on Canola, Kagu, UKMP etc.. I know early on in the development of UKMP Konttori had spoke of adding in visuals but I don't know if he dropped it in favor o battery savings. It would be nice though if the dev "would/could build" in this "feature" then leave it up to the end user to turn it on or off (toggle) to preserve battery life and possible cpu cycles..
