bag question

[devan69]

not sure if this is right place or not but here goes. I was wondering if there is a in-game setting i am missing or a addon i need for this to happen. i want to get the tooltips for items in my inventory to compare with what i am wearing. like it does when u hover over items in the quest window. it shows a tooltip of both items and gives u info on how much u will gain or loss if u equip that item.
