The following screenshots show TrackLink installed on IntelliJ IDEA allowing to work with Bugzilla issues.
TrackLink tool window shows issues selected by Deskzilla query (this list is live and is updated as soon as anything changes in Deskzilla).
The following is TrackLink settings dialog configured per project. Issue link patterns and replacement strings allow to define short notation for issue references.
When TrackLink detects a stack trace in issue's contents, an icon is displayed. Pressing Ctrl+Enter on the selected issue with stack trace brings up IntelliJ IDEA's "Analyze Stacktrace" dialog.
TrackLink allows to quickly search issues for specific text. Issue list is filtered and all inclusions of the search text in the issue's contents are highlighted.
This screenshot shows IntelliJ IDEA's VCS commit dialog with additional option, "Link to Issues". If it is selected, after you press "Commit" button you can choose corresponding issues and commit comment will be adjusted automatically.
TrackLink allows to search for issue links both in source code and in VCS history.
