= FogBugz = A popular commercial bug tracker, which even gained a web interface and integrated wiki over time (I wonder where they got the idea). Covers more or less the same ground as Trac, see their [http://www.fogcreek.com/FogBugz/details.html feature list] for inspiration. Some people are even using FogBugz and Trac together, the former as a [SeaChange/CompetitionSurvey BTS] and Trac for the Wiki and Subversion browser, see [http://hudora.github.io/tracfogbugz.html TracFogbugz].
