Thanks for the idea!
Currently, you can view master features and features on the same features board using the master feature label on your feature card layout. I noticed that you do have that in your attached screenshot, but if you want to learn more: details in a single view.
Due to this, we are unlikely to implement this idea at this time. However, we will continue to monitor this idea for community feedback to help determine priority in the future. We hope you can understand.
