Is there a way to view the links in IN-A? I can do it through IN-B, but I would like to be able to look at it when doing a lookup in IN-A.

Not sure what the gold chain link is. If I look it up in IN-B I can see a little camera to the right of the link and if I click on it, it opens up the blueprint. But in IN-A there is no camera, and nothing else seems to open it.

That is the Item link if the camera opens it.  Go to Settings, US-A and make sure the Toolbar is turned on so you get the camera icon enabled in IN-A and other programs.
