Right now it's only possible to add or view a reference between a file and another object like Issue, Form or Asset, from "the other side".
It would be extremly helpfull to see and add a reference also from the file area.
Not easy or possible to find out where a pdf is has been referered into (Issues, Assets, Forms)
Also, it would be essential to be able to create a complete report with all the references between the different objects.
