how do i stack 2x in a tool cupboard?

What do you mean ? , the stack size should be the max of what you have configured ?

oh, its because ive seen an plugin where out side of a tc its 2x stacks and when you put stuff in a tc its 4x stacks.. (On rust ops)

Merged post

and im wondering if this is the plugin for that, or i need to do something  else
