I think something neat you could do would be to make an upgrade that will give players the abilities to adjust how much heat a pipe sends in which direction. i think it would help to even out heat flows so that players can distribute heat more evenly across their vent setups. another thing you could add is an upgrade that enables you to control the efficiency at which the cells run. lets say for instance we ran a lvl 3 uranium cell. what the upgrade should do is make it so ir runs at only 50% so on base levels instead of it running at a full 16 power i think 36 heat to only 8 power and 18 heat. i think that would make it so that those that want to run their reactor at a slower rate they can. so it wont overload. and maybe make it so that it runs at double the amount of ticks due to only half efficiency.. just a couple neat ideas. i know it would be a lot of work. but i think it would pay off
