Field Teller is an easy to configure JIRA plugin that lets you display parent issue's custom-field and system-field values of your choice in a convenient panel. You can choose whether the fields you want to display will be placed on the left hand side or right hand side of the issue view page. Field Teller also lets you selectively design the fields to inherit from a task which is organized in a configuration panel.
