The mod itself is absolutely a must have for me, except for ONE THING...... the swap from being able to craft in inventory to an assembling machine only recipe. Can we get a mod option toggle for that, pretty please with a cherry on top?

Adding a startup option should be simple enough.
Won't change the recipes requiring lubricant though, as fluid recipes can never be hand crafted.

Love it! Now..... can you reverse port that to the 1.0 version? I'm not jumping to experimental this time around.

No, I only support the latest version of my mods.

I'm interested in what this mod does - however, i cant build locomotives neither by hand nor assembly machines. Maybe because of an other mod like industrial revolution2 mod. I just struggle with getting things going which is a real pain. But I like the more thoughtful utilization of rails and trains, fluid and electric trains, war- and cargo-trains.

All my mods are for base Factorio.
I can't put in the time for supporting total conversions like IR2.
