Problem
Currently, you can only fold/unfold headers and lists.
In my workflow, folding headers and lists serve different purposes.
I fold headers to eliminate visual clutter and narrow my focus.
With lists, however, they have a meaningful structure; some lists are folded and others unfolded. I find folding all lists not useful at all. Even if I were to fold all lists, I’d want to fold only the topmost level, not all levels.
Possible solution
Add options to separately fold/unfold headers and lists.
Add an option to fold only the topmost level of lists.
