my problem is that on long files I often fold a certain number of levels. When I close Obsidian and reopen it everything is unfolded again.
By reading different topics in the forum, I understood that either everything was folded up and Obsidian kept the memory of it, or else when it reopened everything was unfolded. The only solution is to use the Creases add-on
Is this the case or is there a way that I missed ?
