I'd like to suggest to add NFC switch to top notification drawer buttons.
Right now it requires entering a couple of sub-menus. Adding the button would also increase security - especially when one use Android Pay or other payment application that uses NFC.
I agree, I personally like to have quick on/off access to all the communication options on my phone. It's one of the things I found so annoying about my Lumia, that I had to take ~4 gestures/taps to turn off mobile data! On my N8 this is swipe down and tap, easy.
