Hi, I have a feature request, and felt the best way to describe it would be with simple scenario:
- As I am working around the house, AudioRelay is transmitting audio to my phone via WiFi
- I sit down at my PC and know that I have atleast an hour of free time, so I connect my phone via USB
- AudioRelay detects the USB connection and automatically switches to the USB tethered IP Address.
- Break time is over, so I disconnect my phone from USB and put it back in my pocket
- AudioRelay detects this and automatically switches back to the WiFi IP.
- I sit down at my PC and know that I have atleast an hour of free time, so I connect my phone via USB
There is my suggestion 
. Thank you and great work!
