One Workflow
As a developer, you're already overloaded with information. Emails, customer issues, bugs, documentation. FogBugz does an excellent job of allowing you to manage all of that information through the use of filters and notifications. Kiln extends FogBugz' workflow by implementing code reviews as FogBugz cases.
You can search and sort reviews from FogBugz, add them to your customized filters, subscribe to them for change notifications, and star them for later reference—just like you do right now with your cases. Because code reviews work with your existing FogBugz workflow, they're trivial to add to your routine—not a bolt-on afterthought like other systems.
