Diablo /BG Style Inventory

Diablo /BG Style Inventory

Hi a question
I'm looking for a Diablo/BG style Inventory ( to make it clear an Inventory with one Slot in te middle, one at the top, one left, one right, one below and one anywhere else).

Does anyone know how to do this ABD is it possible to create an extra Inventorfrom where you can carry things or use potions but you don't get the item bonus?

Thnks for your halp already
i would be glad if someone could help me with this,

Look at systems, mainly Vex InvX it is cool but hard to implement.
