"Expand / Collapse" - suggestions for improvements (1)

How is it today?
To collapse a subtree, the cursor must be in the root (parent) block of that subtree.

Improvement proposal
With the cursor in a child block (say, block D), when using the shortcut to collapse:

1. collapses D ("hides" D's children, if any);
   1.1. if there are no children of D, the situation is the same as in item 2 below;
2. when the collapse shortcut is repeated afterwards, the immediate parent of D is collapsed (and the cursor ends up in that immediate parent, say C);
3. and so on.

For an example of this proposal, see how it is done at https://tana.inc/
