This is a plugin for Mantis Bug Tracker (MantisBT) 1.2, 1.3 or 2.0. It adds the column "Relationship" to the view of "View Issues". This column shows the existing relationships of the registered Issues. The color of the status can be displayed optionally.
Copy the 'Relationship Column View' plugin just in the plugins directory of Mantis. The parameterization of the plugin is done with the configuration dialog.
With 'Manage / Manage Configuration / Manage Columns', the new column 'relationshipcolumnview_relationship' (from 'All Available Columns') should be placed to the view 'View Issues'.
