That's the first thing I always check for after an update and every time I am disappointed Why they can't enable such a basic and useful feature I don't know. It's a shame no-one has created one for the PS Studio. If I had any free time I'd look into myself!
I agree on this one. Should have been included by default, even if it drains the battery. Now though I feel they are probably focussing on a huge update aroundPS4s launch.
