I am not sure whether this is a bug or feature request. Could not find anything in the help docs.
Things I have tried
What I’m trying to do
I have a nested list open in my note. The note is open in Edit and a Linked Preview mode. I click the side triangle (not sure what that is called so couldn’t search) in the edit mode.
I assumed that list in preview pane will be collapsed. It did not.
I changed to a different note and opened the original note back. Now, both lists are collapsed.
