Harou all!
Lately i’ve been playing and I thougth “Would be cool if it have some way to know if the stockpile is full 
”
“But, man, if they do that, will have a visual pollution!” I agree, BUT I think the stockpile could have a “check box” to u mark if u want that notification or not.
“But… In what way?” If u see the storage items, especially, for example, supply rack, when u place the it, it’ll notify u to select a item.
My idea is: When the stockpile item is full, a notification stay above it, to tell u “Hey, it’s full, bro”. And another thing that would be great is when the stockpile is almost full, then u have a yellow exclamation, maybe?
Well, that’s my suggestion xD
