Right on! There’s quite a bit of theme dependencies you’ll need to setup first but once you get past the configuration, doing the actual layout is super easy, just time consuming.

Once I had my display panels setup, I made a kiosk user that defaults to the screen I want and then used a unit file on the raspberry pi, configured to log in on boot to the display user and chromeium is started on boot directly into kiosk mode in full screen.
