A killer feature for me would be a control that helps my device switch contexts. I fiddle with about 5+ settings whenever I prepare to leave home, board the bus, or disembark at my destination. That includes toggling WiFi or finding an SSID nearby, toggling mobile data, Bluetooth, battery saver/brightness, DND/ringer, etc. Why does a general-purpose smartphone force me to manually press all these buttons in a checklist sequence that's easily forgotten? Why can't I just configure one green button that says "Leaving home" and it executes all those settings on my behalf? Another red button that says "Arrive at church" and it goes silent/off-net/DND? And why, when I turn the phone's power off and back on, it restarts with all the same settings even if I've switched contexts? If I shut down a noisy connected phone, I can't turn it on at church because it'll gratuitously probe the network, use mobile data, chirp with texts and calendar reminders. So even better than those aforementioned buttons would be geofencing, that allows me to configure where DND/ringer is on, where BT, WiFi and mobile data are allowed, etc. If a device is going to feature dozens or hundreds of fiddly gadget preferences, please allow users to create "big knobs" or scriptable actions to simplify them!
