It’d be nice if there was a option not to let forged and unforged items stack together.
I’ve had to play Where’s Waldo with my forged tools a time or two
But I do like to keep one unforged in each stack for picking up trash.
I know it takes way more space but when moving around forged tools I place them manually without shift click and keep them (in storage) in stacks that are all the same exact tool.
But still I support this suggestion.
Saying that, I still like having a single stack of hammers in my inventory with several different forged hammers. When mining I like to have a full AOE, a hard 1-hitter and maybe a horizontal or vertical AOE. Saves a lot of space if I can still stack those.
