Would be great, now that folding in preview works, that it would sync over to edit mode as well and the other way around. Example:
You fold down a header in preview, switch to edit, it’s folded there too. At the moment, these things doesn’t sync. Same way, if you have something folded in edit, you would want it folded in preview as well.
As I experienced today, I folded a couple of headers in preview mode, then wanted to edit something visible in preview, once I went into edit mode, the thing I wanted to edit was now at furthest bottom of the page. And when I wanted to go back, it was unfolded again.
