I was playing a game of DA (latest update).

One of the AI races owned an exclusive control trade good (hull plating) which I traded for.

Later on, when I was on the diplomacy screen again, I noticed that hull plating was again being offered for sale to me by the race that owned it!

This raises a couple of questions ---

Currently, I don't know of any way to show what exclusive control trade goods I have successfully traded for. Perhaps the game could show them on my race's diplomacy screen in the exclusive control goods area but in a different color?

Also, I notice that, unlike other tradable goods, right clicking on an exclusively owned trade good does not put up a screen to show the trade good details. Could this be added?
