I noticed that at least in latest SFOS 4.5 (but I think it was the same also previously), if one searches for bluetooth devices with Settings → Bluetooth → Search for devices, the device is shown either by its name or by MAC address if the name is not set.
As the names are not necessarily unique (often they are just the BT device model), I’d like if the UI would show both name and MAC address, either using two lines for the list item (bigger font for name, smaller one for address) or maybe in a single line like “DeviceName [XX-XX-XX-XX-XX-XX]”
