Lets say I have a girlfriend or a busy who sends crazy text/pics and during a meeting at work. I was wondering if the do not disturb feature stops messages except from the group of interest. Like work group or emergency contacts group. If not I think this could be a great feature for business use. Also make have this feature applicable by the calendar as well. A simple drop down to select labeled do not disturb or that half moon icon with a drop down with a null value that means not applied and on and the groups list. This way I or we can have it for every meeting. I can see many applications for its use. Girls friends house, funerals, parents dinner and so on. But still gives you the security knowing the important content will get through.
