I am just curious, how might I go across creating a custom GUI inventory? Like instead of the Core Inventory GUI I could make my own Inventory GUI. Problem is I have alot of experience with GUI's, but I am just learning to tweak Core GUI's, and I have an idea about how to make it, just not how it could be interacted with and saved for when a player returns, if that makes any sense.
I am not a scripter but this is my best.
Create new bools inside the player for each tool. And save the bools
