So this is really specific (and maybe based on a misunderstanding), so probably not worth it, but i'll say it anyway.
There's this (new?) Alien Artifact called "Integrated Thermoelectric Network". Once you have >50 natural heat dissipation, ITN's effects confer effective immunity against all side effects of heat, since it seems (this is the part i'm not entirely sure about) to activate after heat production and before heat dissipation.
Because all side effects of heat (except lower evasion rate) can only trigger when at >=200 heat after the dissipation phase, there's no way to suffer those side effects anymore once you have >50 natural heat dissipation. (Number after heat production gets "capped" to 250, heat dissipation lowers it to below 200.)
Because of this, heat warnings are effectively useless (unless you care about the lower evasion rate thing) and even annoying.
After getting ITN in my latest run, i ended up moving the heat warning setting from 100 to 300.
Next run : "Why do i keep failing to notice i'm overheating?" (I forgot to move the setting back down.)
My suggestion is either a setting to reset the heat warning setting at the end of runs to a specific value, or a setting to disable heat warnings when heat side effect immunity is acquired.
Again, very specific, possibly wrong, and probably not worth it.
