Proper airplane mode
This is a suggestion about how airplane mode works in gnome based system. The airplane mode option is available in the wifi settings when wifi is turned on. Issue 1) This, I think is a wrong place for it. 2) It functions a bit weirdly check these screenshots:
[Normal wifi on]
[Airplane mode turned on. Disables wifi bluetooth etc. Yet available in wifi menu. Secondly, the whole wifi menu blanks out after airplane mode is turned on]
[Issue 2)Airplane mode turned off means all networks are turned on! Bluetooth and all even though they were off before turning on airplane mode]
By usual means, airplane mode is supposed to save old state of different networks and restore them when turned off. (This is how it works in android and even windows if I remember right)
