Another citizen-designer idea for city dwellers. In large, well-trafficked buildings, it’s not uncommon for someone to race for the elevator door just as it’s closing. If I’m the guy inside, I usually try to help. I reach for the button panel, scrambling to find the “Open Door” buttton before it’s too late. It’s kind of a game. How good are my reflexes? Will I be fast enough? Here’s my point. The button is unnecessarily hard to find. Why not make the “Open Door” button larger than the others and bright green?
