Is there an existing issue for this?
Summary
As a user I want to be able to see all the work items in their hierarchical order and expand each level separately such that I have a better overview over all the open tasks.
In Azure Dev Ops this is solved like this:

Ideally, this is built into the existing list view or added as a completely new view "Hierarchical List View"
Why should this be worked on?
With the new hierarchical order in the enterprise grid subscription (https://plane.so/blog/introducing-workspace-work-item-types-hierarchy), the need for a better display option for visualizing the hierarchy is critical.
