Both products are feature rich and have many alignments which would be great to keep in sync.
- Aha! Feature Type - FogBugz Case Category
- FogBugz has an "Area" concept which doesn't map directly. At least being able to select the target area for new cases would be a start.
- Aha! Releases - FogBugz Milestones
- More complete mapping of workflow to status (kind of like the Trello integration does)
