Stash & Inventory Slots

It would be really nice to set up inventory slots that would accept ctrl+clicked items like so:



Ideally you could set up a maps tab to slot the maps according to tier or name even.

EDIT: The edit button lets you draw rectangles and set the size of loot that can fit as you see in the diagram. When you are done editing, the different colors may tint the inventory perhaps, and it would be good to have some kind of UI describe what can fit in each inventory slot.

This is probably an easy enough addition to custom tabs however I would recommend an empty stash tab requirement before the player can edit each tab's configuration.
