I think there are two ingredients in here, that SB is missing:
- persistent fold/unfold - there already is a related github issue, but basically it originates at @nickb request → Add a option to SETTINGS to let the frontmatter folded status be persistent · Issue #1058 · silverbulletmd/silverbullet · GitHub
- UI/UX design on visual folding/unfolding, that’s interesting
My huge vote on persistent folding. This, plus keyboard shortcuts would get us 99% there in terms of usability.
Let’s see how the issue unfolds 
@nickb on the front matter case, there is a partial solve, hiding it with space-style, see here
