Were you aware of https://mods.factorio.com/mod/blueprint-variables before making this? Seems to do relatively the same thing. Not to discourage you, just curious.

+1 to to this question. Does this mod differ significantly from Blueprint Variables?

I wasn't aware of that one no
from what I can see the main difference is being able to set recipes? I'm not able to test it at the moment

Recipes would be nice. At the moment I'm using Blueprint Variables with the Crafting Combinator mod.
It's a little extra effort but holy /wow/ does it work a treat.

The main difference is the use of one parameter. The other mod use parameter for fluid and a different one for item, which is a problem for station name. Since if you put fluid and item parameter in the station name, you will be leave with a parameter not used nor removed in the station name.
From what I see, this one is really close to 2.0 while the other one is more 2'ish
I used both.
