"Backlog Management" is missing documentation

In the feature overview table (https://about.gitlab.com/pricing/gitlab-com/feature-comparison/), there's an entry "Backlog Management" with a tooltip that broadly explains the feature. However the feature seems missing a documentation page and it's not really clear how this feature looks and what it adds. As a potential buyer I'd like to see a documentation page where this feature is explained, with screenshots, like most other features are.
