budboard is designed for flexibility, so you can choose what you want to show on each screen.
To change which product categories a screen shows, log in to the budboard Control App and navigate to Settings. Here, you will see all of your screens at your current location.
To change what a given screen is showing, simply find the screen you want to modify and use the "Category" dropdown to change which product category that screen shows.
As always, remember to save your changes!
