I was trying to make all unresolved links a different colour, and noticed that when creating my css I couldn’t find anything related for edit mode (view mode is fine).
Then I saw this thread from October 2021 where the last word is that it was supposed to be implemented after 0.9.4
Maybe I misunderstood? Because when I look at the Inspector in editing mode, I can’t find any indication of anything displaying “link not resolved” the way I do in view mode.
