Add config file for edit reactor component's parameters.
For example: vent's power, rod's heat generation.

Sorry but no.
We have to provide consistency for setups

Is exist another method to edit thease parameters?

@Roma32e32 TLDR We have to provide consistency for setups

We provide examples that simply would no longer be reliable the moment we add such a config.
And reactors are already with a really bad stigma in the first place.
Such customization is simply not feasable with everything in the works.

Is exist another method to edit these parameters?

Create your own components via addons :)

Ok
