Playing this mod for the first time, I'm having a blast with how puzzling the mechanics are. Albeit a bit of a slow start overall, its a fun challenge.

I would like to see the decompilation recipees in the inventory, maybe in their own tab. Its really tedious to look up what letters turn into, as there are so many recipees (alt-left click shows all of them).

Also: Fish should respawn somehow. It feels extremely off to the design philosophy of "scale to the mega" factorio has in general to just kinda have to min max fish usage, when what i really want is scale up production.

second to the showing recipes in the inventory!

I am not 100% but H becomes pretty abundant from heavy oil barreling, i personally havent reach that point yet, just unlocked blue science in my last playthrough but I anticipate that tonight I manage to get heavy oil :D , for F Solid Fuel becomes really "easy" way

Having the letter decompilation recipes appear as a dedicated tab in the inventory once unlocked is a good idea. And it's certainly warranted too, given how much I've seen people miss M's from W's, H's from A's, etc. in the early-mid game. Once I'm done with midterm season, I'll see what I can do ^w^
