Features can have relationships with other features recorded and this is really helpful for building out the overall feature architecture when they're "visualized". It would be great to have functionality to display an overall features visualization for a Release / Initiative that could be uploaded to a notebook. We would use something like this to share with our dev team to show them how it all wires together and to help our UX designer too.
This is possible today by setting Record links with Features and levering our interactive dependency map.
