Item link indicators broken?

[vamp07]

I was wondering what happen if I delete the last item I may have linked in many places, will I get an indicator that I am about to loose something that is not repeated anywhere else? When I linked I realized that both items get a little indicator in their icon that there are links. This is cool. I then deleted the link but the original item still had a link indicator. A full refresh (Shift-F5) did not get rid of the indicator. I think an optional prompt that you are deleting the last link item would be nice. As you link stuff around the outline it's going to be easy to delete items while assuming it is still repeated somewhere else.
