The problem starts when you improve weapons on the grindstone. Currently my two swords are listed in the inventory like this:
Skyforge steel sword (2)
Once improved on the grindstone they now appear as:
Skyforge steel sword (Superior)
skyforge steel sword (Superior)
Since they now appear as two separate items instead of one item x2 they can no longer both be assigned to a single quick slot. What this boils down to is that I have the choice of keeping my swords basic for quick access to them, or I upgrade them at a cost of having to stop to tit about in the menu each time I want to switch from my bow to my swords.
Has anyone else run into this? Or better still know a way around it? I sure hope so!

But they get shown up as 2x Sword XXX
