I cant think of where to find a list but theres also the scene where you take Cyan to Miranda in the WoR to talk to the woman hes been sending letters to (and replace the letter on the desk)

And Theres also shadows four dreams which occur if you rest at an inn with shadow in your party.

Theres also one where you take Sabin to a small cluster of trees that form a + sign on a small island north of narshe in the world of ruin.
