Constantly finding new things. Setting up a new model you have a choice of what you show on the main screen (s) (You can have multiple screens to swipe through)
But if you find you have the requirement for more widgets showing on a single main screen than you have spaces for, I notice that if you select both battery voltages on the same widget it alternates between battery 1 and battery 2. The last shot you can see on the right hand side I selected two widgets, one for each battery.
Such a clever bit of kit!
