Use Case / Problem
I’d find it useful to be able to fold everything except a specific entity (heading or list).
Proposed Solution
There could be an option called Fold All Except.
While holding a key pressed and clicking on the folding symbol of a heading or list, everything except that entity would be folded.
If used on a heading:
- All other headings would be folded.
- All lists within it would be folded.
If used on a list item:
- All headings except the parent would be folded.
- All other list items in the parent would be folded.
