Fujitec eases bottlenecks via SlashdotWhy has this taken so long to invent? This seems like the most straight forward thing in the world to do. Actually, even easier, why can't I just unselect a button that I've accidentally selected? Or how about when I get in the elevator if there is no one in it and nothing is selected and it says "going up", when I select something, could you just go that way instead of closing the door and reopening it for ... no one? Thanks.
