List of all missable opportunities???

Is there a list of ALL the minor missable opportunities, interactions, etc in the game??? I accidently got the Faydown Cloak before getting kidnapped and recently found out that I can't do that interaction anymore. Also there are apparently a bunch of NPCs that I might accidentally kill if I do certain things. Does anyone know of a list with small things like that? (So far I can only find lists with big things like if you get to the Citadel through Sinners Road in act 1)
