Provide ability to customize Issue Links display within an issue

Request Summary

• Ability to define what fields are displayed in issue links section. Should be able to add as many as possible including customized fields.
• Provide headers in order to allow one click sort ability on selected fields

Request Background
I would really like the ability to customize the information displayed within the issue links section. A current example is that I'm building out a request to use Jira for project tracking. I've created a 'Project Tracking' issue type for that, and all enhancements/defects across projects will be linked to the issue type. However, I would want to customize the display so in addition to the summary I could see the Status (not the tiny icon) and also other custom fields, such as 'Schedule' so I can see if the linked issue is behind/on/ahead of schedule, as well as the Fix Version for issues. I'd also like to one click sort by the links instead of having to go into the back end and manipulate a file. When having a large number of linked issues, being able to manipulate how we view the data would be hugely advantageous.
