[Feature request / Help] Setting / changing default fuel (pyanodons)

[isaacsantos2001]

Hi.

In py early game (first 100+ hours) most things consume fuel, and there are many types of fuel.

I can't figure out what yafc chooses/sets as the default fuel and I would like to change this - it's important to calculate fuel input, and many chains are long leading to me clicking to set coal fuel on every single machine when yafc is setting them by wood at default.

I think it has something to do with previous choices, or maybe unlinking but I am not sure
