Do Not Disturb mode to be accessed easier..

Just a suggestion.

Do Not Disturb mode has been a great addition and I use it all the time to keep the phone at bay at night.

It would be great if the switch for the mode was more accessible, as opposed to having to go through Preferences and such.

Perhaps when pressing the top button as if to turn the phone off (to bring up the Slide to Turn Off switch), there could be another slide switch for the Do Not Disturb function.
