The guided Bugzilla page contains some very irrelevant fields (reproducability; expected results) for documentation (and bugzilla) bugs. Reproducible: Always Steps to Reproduce: 1. 2. 3. Expected Results: For usability I expect that the irrelevant fields are filtered out.
Those parts can be left as-is, at their default/empty value. I do not believe there is an option to choose/remove specific entry fields per product. It would seem to require an inordinate amount of specific coding for such an implementation. -Jeffrey
