link panel shows what layer the (missing) link is on and/or makes 'go to link' work on hidden layers too.
When links are missing that are on a hidden layer there is no way to easily spot them and check on in multilayered files. Since the GoToLink function only works on active layers, there is no other way but showing ALL layers and then using this function, remembering the layer and then hide the layers again; a painstaking procedure with large multilayered files. Would be nice if the link panel would simply state on which layer the missing link resides. Or make the GoToLink function automatically make the appropriate layer visible, like when pasting onto a hidden layer with 'paste remembers layers' on.
