Airbus just changed the interior design of A330 / A340, with round-shaped doors for the articulated bins and door handle of round design, thus making them look better.

But there is a drawback: The reading lights, ventilation controls and oyxgen masks are now all located at the centre position of the centre bin, so providing less privacy and convenience, as well as more disturbance when the reading light is lit. This is different to old design, which each side of the centre bin consists of 2 reading lights, ventilation controls and oxygen masks for each row, thus providing excellent privacy and lowest disturbance.

So I think Airbus could change the design of centre bin, with contours same as new design, but with reading lights, oxygen masks and ventilation controls placed on each side of the bin in pair like that of old design, so to minimize diesurbance and maximize convenience.
