In preview mode（ ![[This Note]] ）, can I completely hide notes that do not exist yet? I mean to make the reminder to create a note disappear.
It used to be possible：Provide "note not created yet" in preview for embedded note that doesn't exist - #2 by sam.baron
Moving this to #help. I would think that you can target this with CSS.
You can put the notes in comments:
%% ![[This Note]] %%
