Can you make it so that every item config has a "Keep vanilla" option which makes the items keep the spawn amount and max values vanilla, having the option off lets you change the current configs.
Also I'm not sure if it's a bug or not but the max item spawn configs are confusing because if I put it at 1 it spawns 2-4 and its the same at -1, 0 works as 0. It's just really confusing and annoying because I wanna keep the item spawnrates and amounts and whatever vanilla, I only want to increase upgrade amounts but the mod keeps messing with everything else.
