A number of our Product Managers had started using Master Features for their ability to combine Features that were more detailed than required for high level Roadmaps. However we quickly learned that viewing and reporting on Master Features and Features is binary - only one can be shown at a time.
What we'd like to be able to do is view and report on Master Features and Features together in the same view. Naturally this would mean not showing Features that are included in Master Features so there is no duplication. This would allow us to include Features where there is a singular Feature that should appear on a Roadmap together with Features collected in a Master Feature.
At this time we have moved away from using Master Features due to this limitation and are employing workarounds (such as creating Stories of Stories) in Jira and Aha so everything appears as a Feature.
