The latest beta v3.60~46 states
“Always show battery SOC percentage or Temperature in Brief center (instead of only when there is one gauge).”
This is true for 1 gauge, 2 gauges and 3 gauges but it disappears if you select all 4 gauges.
My system, like many, is in an RV thus a perfect brief page would be fresh water, waste water, black water and LPG for the 4 gauges and then SOC in the centre.
