Today in a meeting we have realized that a bunch of seasoned bug reporters were all regularly confused by the combo "Dependent Tasks" / "Depends On", just because of the choice of words.
In Bugzilla it is clear:
- "Depends on"
Two verbs in third person with opposite/complementary meaning. Yin Yang ---> Tao.
