2-way links

[quant]

I'm not sure I completely understand your suggestion.
I think it might be close to the "links pane" I suggested some time ago, ie. one should be able to see all the items that have internal link(s) to the current one ... at the moment this is possible to do by creating a search for item title (if you don't change links name), I do this for my library items for finding all the places where my library item is referenced.
