This mod is imba

Yes. I am open for suggestions though. You can however configure many aspects of the mod and even make the game harder (by just allowing more pollution / energy usage)

I can exploit this mod by farming items produced count

Yes you can. You can also just cheat with the console. I do not care.

Can i refactor my factory?

Yes, produced items of deconstructed buildings are stored in memory until you construct another building of the same type (assembler / furnace).

Please do miners

At the moment Factorio API has no possibility to catch miner events that are easily usable, so it is not implemented.

Assembler X / Furnace Y in Mod Z is not supported

I do not consider other mods at the moment. I do appreciate suggestions or even PRs for other mods though.

My Factories / Smelters do not get upgraded

Due to bad performance the surface is scanned in small chunks at a time, It may take a while to update your factory. Be patient on huge maps.
