A pile of bizarre design decisions, too low voltage, should be sold with a plugpack, shouldn't need two PCBs.
Even it's one distinguishing feature of BT GUI control is crippled by it's ridiculously low information density GUI. For multiple supplies they shouldn't use windows, the GUI should be designed suitable for multi-supply use with the GUI layout corresponding to the physical layout (to slightly reduce the usability loss of not having a quick way to see what wire corresponds to what voltage as you can with a traditional supply).
