Do not show master features in user story maps when I have those disabled on my product. It confuses my users and takes up way too much real estate.
Thanks for the idea!
It is now possible for product owners to choose if you would like to display master features on your product's user story maps. From your user story map, click on the [...] menu and select Manage master features. Enabling or disabling master features for your product will control visibility of the master feature row on your user story maps.
