Preference setting to turn off "close to max" thermo readout warning state

When just one of the sub-thermos are close to max, that high-level thermo will glow red warning you and the thermo readouts will always be on-screen. It feels like you're being told off (and warned, which is the point), but if you know what you're doing... it serves no purpose but you're still being told off (or warned) constantly.

Please add a preference setting to turn that behaviour off. Preferably in a way that has no warning/telling off look to it and does not show the thermo all the time.
