Similar to Airplane mode it would be nice to have a button which disables all networks connections. This could be used as panic button if one has the feeling that all data transmission should be prevented right now.
Then why not use the airplane button in case of panic?
Nevermind, airplane is obviously only for wireless :)
I don't really see a point in adding such feature. You usually have one or two active connections at max, not counting VPNs, as those get killed automatically when you kill primary connections so how does this help if it saves you one click?
