Is there a way to easily turn off/on all notifications at once on Android devices? Scenario: I'm currently using my Nexus 5 to Chromecast and that's about it. It stays on my nighstand for when I want to watch stuff in bed. I obviously can't turn on Airplane mode as it requires a WiFi connection to the same network that my Chromecast is connected to. While the N5 is being used like this, I don't want the distraction of notifications. I'm not talking about sound or LED, I simply don't want anything pushed to this device. I know that I can disable notifications individually, but I have way too many apps to do this back and forth on a regular basis. Any tips or suggestions?
