Okay, so you are telling me that the current (absence of) shortcut is intentional. How do you know that - do you work at Larian?
Mind you, "Mark As Wares" shortcut was also absent in the first EA version, yet they added it.
Also, I've never asked for the "retrieve it with single click" part. This is purely your invention. It would definitely be convenient, but it will make inventory economy unnecessary, and would severely impact immersion, or what's left of it.
