We have a standardized structure of phases that we use to connect upstream R&D components to downstream products. We'd like to filter so we only see limited Phases/Milestones to be able to more clearly (less cluttered) see the dependencies and timing of the related components/products.
Thank you for the idea. This is possible today by adding a release phases filter to the Gantt chart. The status of this idea was out of date. You can learn more here: Customize the Gantt view.
