Hi. I've been waiting for the original mod to be updated, so thank you for taking the time to update it!
Would it be possible to make the fluid amount to be a mod setting?
Reading the history of the original mod, the amount it had was intended with the current fluid system. (v1.2.2: Compatibility with Factorio 0.15. Increased water output 10x to match change in vanilla liquids. Adjusted icon size to the new 32x32 requirement.)
I liked the fact that it was under powered as you say, so it won't be a "cheaty" way to get water...
Maybe even get a research path that upgrades the fluid amount, but at the same time require more coal? Or different tiers using different types of fuel, idk..
Edit: Ah I see you mention that in the description... Well I'm leaving it up here so you see that it's interest in that.
Anyways, thanks again and a happy new year :)
