As the flic buttons are understandably pricey, I think there should be an option to locate the flic when you lose it.

I know adding a feature like that to the button physically/mechanically would be vexing and would cost more money so I have a better solution; creating a software feature for the phone and device that tracks the bluetooth connection to the device.

Using this feature would not allow you to see the flic's live location, buy it would allow you to check where your phone's location was the last time it was connected to the device.

This way, you at least have an idea of the last approximate location the flic was at before it disconnected from the phone via bluetooth.
