• Not sure it works but seeing that it doesn't have and shared I/O like the OG Fusion Reactor.
• Not sure on the fusion reactor thrusters since it keeps favoring the left side or is there a proper ratio?

It might exist simply because the reactor is copied from the vanilla one. I wasn't directly intending to include one but I'm not opposed to implementing it

it can be added since it can give a lot of options for layouts on oddly shaped ships especially of you are trying to make a very compact ship.

Currently it does show a neighborhood bonus, but the thruster doesn't actually care about the higher plasma temperature. Having 2 reactors per thruster looks strange, so I was hoping to affect the ratio with adjacency...

If the thruster accepted a plasma connection from the top (and either adjacency affected output rate, or thrusters cared about plasma temperature), it would even be possible to use 2x2 reactor arrays for the fusion thrusters...

Perhaps it would be a better idea to internally represent the thruster reactor as a nuclear plant (burns fusion fuel into heat) connected to a hidden "boiler" turning heat and water (/maybe another fluid?) into plasma production...

I think it would make a lot of sense for the fusion thruster to care about the higher plasma temperature, it would incentivize larger ships for more efficient thruster fueling.

this is offically planned once I get FluidEnergySource to work
