ModernX was built during a Theme Workshop live stream. If you are interested in creating themes, subscribe to the Unbroken Software YouTube channel.
I stumbled upon an image of a store page for an Xbox Series X. This is my take on what I saw in the image.
The theme and the COMMUNITY Theme Creator project files can be downloaded here.
This theme is a hybrid of using the COMMUNITY Theme Creator and editing code to add the new coverFlow FlowControl.
Because of this, the project files will not contain the new flow control. If you would like to edit the project files and publish the theme, you will then have to manually add the flow control code back into the platform and wall view. Those can both be found in the theme files.
