Battery status labels

My tempest is at 2.36 V, but the status in the grid panel still shows “good”. That looks to me like a misrepresentation of reality, as the next step would be that it completely powers down when the voltage drops to 2.355. “Very low” seems to be more appropriate.
Perhaps change to labels to reflect the current power save mode.
very good (mode 0), good (mode 1), low (mode 2), very low (mode 3)
