Another use case: when I arrive at home, I close my bluetooth headset which would turn-off bluetooth
Or: when I pair my headset, I do not want idle to affect the internet connection (using priority of rules)
Or: when I pair my bluetooth speaker, I put flight mode on to avoid receiving some notifications alert
Or: when I pair my bluetooth device, I launch podcast player or music player (depending on the device)
...
And for me, it would be essential too to play with wifi scanning (separate application is fine but more troublesome )
