⭐ Suggestion
VS Code recently introduced a new API for displaying type hierarchies:
This api is very similar to the exiting call hierarchy api and displayed in a similar way in the editor
Although type hierarchies are most useful for languages like Java that use inheritance heavily, they would also be a nice feature to support for JavaScript and TypeScript
