When selecting an item from my inventory while the shop is open, it would be nice if that item became the "focus" in the shop window, so I could see any other items that are associated with it (like are shown when you normally browse through items at the shop). I often come back to the shop knowing that I need to get some other items for a build, but I forget exactly where the item I was building up to is located, but I know the items in my inventory are associated with it.

Unless there is already a way to do this that I am missing?

+1 to this. As im learning the builds it would be really helpful to jump around to the items i already have.

It already does this?
