Doing Thermo missiles on ships that generate heat without being in combat is an utterly painful act. Either you need to be always shooting missiles anyways, or you need to add radiators.
Now these cut into the heat generation you want to shoot missiles with.
What happens is you turn them off for combat and back on afterwards. But stupid me sometimes forgets about this and I burn my ship down for literally no good reason.
What we need is a setting for radiators to only get rid of heat after a certain threshold in the network has been reached. This would be a huge QoL update
