Sometimes dependency trees and graphs get very complicated, but what I usually care about is either: A. bugs in my product B. bugs directly blocking my product but not: C. bugs blocking bugs blocking bugs in my product Note that unfortunately in some cases my product might actually be two products (until i dream one of them away), so it needs to be a multiselect. For the example bug given above, 363154 maj -- PC email@example.com RESO FIXE [TB-3a1] Improper RSS Display After Todays(12/8/06) Auto-update 363276 nor -- All firstname.lastname@example.org RESO FIXE Header bar no longer full-width 363466 maj -- PC email@example.com RESO DUPL RSS preview is 60% narrower than it should be are not in core, so for option A, they'd be excluded. If bug 363675 which blocks bug 363154 was not already directly listed as a dependency of bug 300030, then it would be excluded for option B. Sorry about the example being kinda bad. I don't usually look at dependencies.
