FogBugz users who develop in the Eclipse IDE should have a serious look at Foglyn, an Eclipse plugin by Peter Štibraný that allows you to view, organize, and manipulate your FogBugz cases without ever leaving the IDE. 

Foglyn smartly builds upon the Mylyn task management interface to make it perfect for use with FogBugz:

• Easily run a search query returning a list of cases you care about, and view subcases in outline format
• Edit cases using a powerful form interface
• Embed hyperlinks to FogBugz cases directly in source code
• Easily tell FogBugz what cases you're working on by activating them right from the IDE

Eclipse users can visit www.foglyn.com to download the plugin and try it free for 45 days.
