Collapse and expand selected folder

Use case or problem

It is impossible to collapse/expand a selected folder from the Files left hand-side pane. We can only use the Collapse all button since version 1.0, but this affects all the folders.

Proposed solution

Add Collapse folder and Expand folder option in the context menu after pressing RMB on a selected folder.

Current workaround (optional)

Use a Collapse All community plugin.

This issue has been closed, and actually, I cannot see that the hotkey has been implemented: Keyboard shortcut to collapse folders / collapse all.
